What is "This is important information for you"?

"This is important information for you!" is an email scam. Scammers behind it seek to extort money from unsuspecting people by threatening to proliferate screenshots that have supposedly been made using recipients' webcams. They claim that they will proliferate these images unless a ransom is paid within a specific time frame. Ignore these emails, since the claims are false.

This is important information for you spam campaign

The "This is important information for you!" email states that the person who sent it has hacked the recipient's operating system and gained full access to the email account. The sender claims that the computer has been infected with a trojan via a critical vulnerability in the router's software.

This malicious software has apparently enabled the person to steal data such as browsing history, files stored on the computer, telephone numbers, and email addresses of all contacts.

Furthermore, the computer webcam (or other connected camera) was apparently used to take screenshots of the recipient and adult websites (that were apparently being viewed), and merged the photos into one. This scammer claims that compromising material has thus been obtained, which can place the recipient in a difficult situation.

The scammer threatens to send the images to all of the recipient's contacts (including friends, colleagues, relatives, etc.) unless $607 (in Bitcoins) is received. Payment is required within 48 hours, after which the screenshots will apparently be deleted, and malicious software installed on the recipient's computer, removed.

As mentioned, these claims are false. The computer is not infected with a trojan (at least not by this scammer) and the humiliating screenshots do not exist. The best option in these cases is to simply ignore the email and do not trust other similar emails in the future.

We receive a great deal of feedback from concerned users about this type of email scam. Here is the most popular question we receive (in this case, relating to a scam that claims to have obtained compromising videos or photos of the user):

Q: Hi pcrisk.com team, I received an email stating that my computer was hacked and they have a video of me. Now they are asking for a ransom in Bitcoins. I think this must be true because they listed my real name and password in the email. What should I do?

A: Do not worry about this email. Neither hackers nor cyber criminals have infiltrated/hacked your computer and there is no video of you watching pornography. Simply ignore the message and do not send any Bitcoins. Your email, name, and password was probably stolen from a compromised website such as Yahoo (these website breaches are common). If you are concerned, you can check if your accounts have been compromised by visiting the haveibeenpwned website.

"I know you are a pedophile", "ChaosCC hacker group" and "The last time you visited a Porn website" are just some examples of other email scams. Typically, scammers claim that they have recorded 'humiliating videos' or taken compromising photos, and will proliferate them unless a specific payment is made (using a cryptocurrency).

The emails sometimes contain various attachments, which cyber criminals send to infect the recipient's computer with high-risk malware. Examples of malicious programs that they proliferate via emails are TrickBot, LokiBot, Emotet, and FormBook.

How do spam campaigns infect computers?

Typically, cyber criminals send emails that contain attachments (or website links that lead to them) including JavaScript or executable files such as .exe, Microsoft Office or PDF documents, archives such as ZIP, RAR, and so on. After opening a file (such as an MS Office document), users are asked to enable macro commands (enable editing).

If they allow a malicious document to enable these, the document installs high-risk malware. Other attachments infect computers in a similar way. In any case, files attached to such emails cannot infect computers unless recipients open them.

How to avoid installation of malware

Do not open attachments or web links in emails that are sent from unknown, suspicious addresses. The same applies to emails that are irrelevant but presented as official, important, and so on. The safest way to download programs and files is using official websites and direct links.

Other channels such as Peer-to-Peer networks (torrent clients, eMule, and so on), unofficial websites, third party downloaders (or installers), etc., cannot be trusted. Software 'cracking' tools should not be used - this is illegal and often leads to installation of malware. Installed programs should be updated with tools or (implemented functions) created by official software developers.

Additionally, use MS Office 2010 or later, since these versions include "Protected View" mode, which protects computers from infection through malicious documents.

Scan your computer with reputable anti-virus or anti-spyware software regularly and keep it up-to-date. If you have already opened malicious attachments, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate infiltrated malware.

Text presented in the "This is important information for you!" email message:

Subject: High level of danger. Your account was under attack.

 

Hello!

This is important information for you!

Some months ago I hacked your OS and got full access to your account -
On day of hack your account - has password: -

So, you can change the password, yes.. Or already changed... But my malware intercepts it every time.

How I made it:
In the software of the router, through which you went online, was a vulnerability. I used it...
If you interested you can read about it: (CVE-2019-1912 - a critical vulnerability in the web-based management interface of the Cisco routers.
I just hacked this router and placed my malicious code on it.
When you went online, my trojan was installed on the OS of your device.

After that, I made a full backup of your disk (I have all your address book, history of viewing sites, all files, phone numbers and addresses of all your contacts).

A month ago, I wanted to lock your device and ask for a not big amount of btc to unlock.
But I looked at the sites that you regularly visit, and I was shocked by what I saw!!!
I'm talk you about sites for adults.

I want to say - you are a BIG pervert. Your fantasy is shifted far away from the normal course!

And I got an idea....
I made a screenshot of the adult sites where you have fun (do you understand what it is about, huh?).
After that, I made a screenshot of your joys (using the camera of your device) and glued them together.
Turned out amazing! You are so spectacular!

I'm know that you would not like to show these screenshots to your friends, relatives or colleagues.
I think $607 is a very, very small amount for my silence.
Besides, I have been spying on you for so long, having spent a lot of time!

Pay ONLY in Bitcoins!
My BTC wallet: 1EnHkXMfZWhtRR1SQU7sxqoAc6hpXCLm8

You do not know how to use bitcoins?
Enter a query in any search engine: "how to replenish btc wallet".
It's extremely easy

For this payment I give you two days (48 hours).
As soon as this letter is opened, the timer will work.

After payment, my virus and dirty screenshots with your enjoys will be self-destruct automatically.
If I do not receive from you the specified amount, then your device will be locked, and all your contacts will receive a screenshots with your "enjoys".

I hope you understand your situation.
- Do not try to find and destroy my virus! (All your data, files and screenshots is already uploaded to a remote server)
- Do not try to contact me (this is impossible, sender's address was randomly generated)
- Various security services will not help you; formatting a disk or destroying a device will not help, since your data is already on a remote server.

P.S. You are not my single victim. so, I guarantee you that I will not disturb you again after payment!
This is the word of honor hacker

I also ask you to regularly update your antiviruses in the future. This way you will no longer fall into a similar situation.

Do not hold evil! I just good do my job.
Good luck.

Subject: Ожидание транзакции.

 

Доброго времени!

Ниже последует важная, сильно касающаяся Вас информация.
Пожалуйста, прочтите это письмо до конца, чтобы избежать последующих за ним проблем.

Пару месяцев назад я получил доступ к Вашему устройству, с помощью которого Вы пользуетесь интернетом.
После этого я наблюдаю за Вами и Вашей жизнью.

Всему виной именно Вы, и ваша потребность посещать порно-сайты.
Эти самые сайты, которые Вы частенько посещаете, и стали путем, с помощью которого я взломал Ваши устройства.

Я залил драйверную шпионскую программу (троянец), который обновляется каждые 6 часов, чтобы антивирусные сервисы его не смогли обнаружить.
Этот софт дает мне доступ к Вашей клавиатуре, камере или микрофону.
Также у меня есть дампы всех Ваших данных, включая фото, доступы к социальным сетям, ваша переписка(очень щекотливая и интимнаю) и все Ваши контакты.

Я подумал: что, если сделать видео где в Вы мастурбируете, а в маленьком окошке поместить видео, которым в тот момент вы наслаждались?
Вы знаете, я сделал это. Результат оказался очень даже... Хе-хе :)

Вы можете нисколько не смоневаться, что мне не сосетавит труда поместить это видео на "порнхаб" или его аналоги и за полминуты разослать ссылку на него всем Вашим контактам.
Не смоневайтесь, результат будет колоссальным для Вас, Ваших родных и близких, коллег и друзей.

Вы можете проигнорировать это письмо, но вы пожалеете об этом! Это не те деньги чтобы, экономить на потере своего лица.
Знаменитый футболист Артём Дзюба - хороший пример...
Ваш итог будет аналогичным!

Это не шутка и не розыгрыш. Все серьезно.

Поэтому вот Вам условие:
Вы просто переводите на мой биткоин кошелек сумму эквивалентную 990 долларам (США) в течении 48-ми часов (ровно 2-е суток).
Отсчет времени начнется сразу, как только вы откроете это письмо, я увижу это.
Найти как купить биткоины Вам труда не составит, поскольку пользоваться поисковиками и браузером вы умеете, это очень хорошо мне видно.

Мой btc/кошелек: 19L8H5WZ8Tfk7VJsXapx6SfciitAVU1cJr, 17eMZxX2fohgmGLQ61KupTQeipeU39aypG, 1HPKwTpog8USNA5MpoGuEkb3xDNUC9eY5o

Как только я увижу Вашу транзакцию, я незамедлительно удалю троян с Ваших устройств. Видео же с Вашими "развлечениями" будет уничтожено немедленно.
Это честная сделка.

Несколько простых правил:
/Если деньги мне не поступят, то по окончанию двух дней, видео будет транслироваться на бесплатных порн. площадках, а ссылки на него будут у всех, кто Вас хорошо знает!
/Не отвечайте на это письмо, адрес отправителя рандомный.
/Не пытайтесь чистить диск. Файл с видео уже меня.
/Это письмо невозможно отследить, транзкцию биткоин тоже, он анонимный. Все продумано!
/Не вздумайте жаловаться куда-либо. Если я вдруг увижу такую попытку, видео будет распространено в тот же момент!

И вот еще совет - заканчивайте бродить по порнушке, да еще такой суровой, вы теряете себя как личность.
Начинайте жить правильно.

Manual threat removal might be a lengthy and complicated process that requires advanced IT skills. Combo Cleaner is a professional automatic malware removal tool that is recommended to get rid of malware. Download it by clicking the button below:

Types of malicious emails:

If you opened an attachment or downloaded a file from a suspicious email, run a full system scan with Combo Cleaner. If you only received the email and didn't engage with it, you don't need to scan anything - just identify the scam and delete it. The full procedure below covers both situations and what to do if you already clicked, replied, or sent money.

Credential theft Phishing emails

Fake login pages disguised as PayPal, Microsoft, Apple, banks, or social networks. The email pushes a link to a near-perfect copy of the real login screen. The moment you type your username and password, the attacker has them.

Common subject lines

  • "Action required: confirm your account"
  • "Your password expires today"
  • "Unusual sign-in attempt detected"
  • "Verify your billing information"
Example phishing email impersonating a major brand
Malware delivery Emails with malicious attachments

Trojans hidden inside fake invoices, faxes, shipping confirmations, or Office documents. Opening the attachment runs the payload and infects the system - often with an info-stealer or remote-access trojan.

Common subject lines

  • "Invoice INV-2026-XXXX attached"
  • "Fax received - 3 pages"
  • "Your shipping document is ready"
  • "Voicemail from +1-XXX-XXX-XXXX"
Example email with a fake invoice attachment
Extortion Sextortion emails

Fake claims of webcam recordings demanding cryptocurrency. Almost always a bluff: the attacker pulls a real password from an old data breach to make the threat look credible, then claims to have video of you. They have no recording and no access.

Common subject lines

  • "I know your password is XXXX"
  • "Your account has been hacked"
  • "I have recorded you - 48 hours to pay"
  • "You have been compromised"
Example sextortion email demanding bitcoin payment
Callback fraud Refund & callback scams

"Your subscription was renewed for $499 - call to cancel." Norton, McAfee, Geek Squad, PayPal, and Wells Fargo variants are all common. There's no real subscription. The phone number in the email connects directly to the scammer, who walks you through "refunding" yourself - which is actually them stealing money from your bank.

Common subject lines

  • "Norton subscription auto-renewed - $499.99"
  • "McAfee Total Protection invoice"
  • "Geek Squad order confirmation"
  • "Your PayPal payment is being processed"
Example fake Norton or McAfee subscription renewal email
Credential theft Account suspension & verification scams

"Your account will be deleted in 24 hours - verify now." The artificial deadline is the whole point: it pressures you to click before checking details. The "verify" link goes to a phishing page styled to look like the real provider.

Common subject lines

  • "Your account will be deleted in 24 hours"
  • "Suspicious activity detected - verify now"
  • "Final warning: account closure"
  • "Action required to keep your account active"
Example fake account suspension email
Mixed payload Delivery & package scams

Fake DHL, USPS, UPS, or FedEx tracking, customs fees, or "package undeliverable" notices. Targets anyone expecting a parcel - the timing alone catches many people. The link hides either phishing (asking for card details to "release" the package) or a malware download.

Common subject lines

  • "Your DHL package is held at customs"
  • "USPS - delivery attempt failed"
  • "FedEx tracking update - action required"
  • "Pay $2.99 redelivery fee to release your parcel"
Example fake DHL/USPS/FedEx delivery notification
Remote access Tech support scams

Fake Microsoft, Apple, or "Windows Defender" security alerts pushing a phone number. Real Microsoft and Apple never email a phone number to call. The number connects you to a scammer who asks for remote access to "fix" the imaginary problem and then demands payment.

Common subject lines

  • "Microsoft Defender expired - renew now"
  • "Apple ID security alert"
  • "Critical: virus detected on your PC"
  • "Windows license expired - call now"
Example fake Microsoft or Apple tech support alert email
Wire fraud Advance-fee scams

Inheritance, lottery wins, romance, or business deals that ask for a small fee to release a much larger sum. The classic "Nigerian prince" 419 family of frauds. Once you pay the first fee, more fees appear (taxes, lawyer, transfer charges) until you stop paying. The promised money never exists.

Common subject lines

  • "Inheritance from a relative you didn't know about"
  • "You won the international lottery"
  • "URGENT - business proposal worth $XX million"
  • "Compensation fund release for fraud victims"
Example advance-fee or 419 scam email
Wire fraud Business email compromise (BEC)

CEO impersonation asking employees to wire money or buy gift cards, or fake supplier invoices with newly "updated" bank details for payment redirection. The email often spoofs a real internal executive's display name and uses an external lookalike domain.

Common subject lines

  • "Quick task - need you to buy gift cards"
  • "Updated banking details for invoice payment"
  • "Wire transfer request - urgent"
  • "Are you available?" (CEO impersonation opener)
Example business email compromise wire-transfer request

How to spot a malicious email?

Phase 1~ 2 min
Spot - identify the red flags

1

Check the sender's actual address, not the display name

30 sec

The display name (the human-readable part) is trivial to fake. Always check the full address that comes after it. Common red flags:

  • Domain mismatch - service@paypa1.com, support@micros0ft-help.com, look-alike domains using digits or extra hyphens
  • Free-email impersonation - any "official" message from a bank, courier, or platform sent from a @gmail.com, @outlook.com, or @yahoo.com address
  • Reply-To mismatch - the From address looks legitimate but Reply-To points somewhere completely different
Why this matters

Real companies own their domains and send mail from them. A "DHL" message from a Gmail address is never legitimate, regardless of how convincing the body looks.

2

Watch for urgency, threats, and generic greetings

30 sec

Scams almost always rush you. The point is to make you act before you think. Treat any of the following as a strong signal:

  • "Your account will be deleted in 24 hours"
  • "Final notice" / "Immediate action required"
  • "Dear Customer" or "Dear User" instead of your real name
  • Threats of fines, account closure, legal action, or arrest
  • Promises of refunds, prizes, or money you didn't earn
  • Spelling and grammar mistakes in messages claiming to come from a major brand
3

Hover over every link before clicking

30 sec

On a desktop, hover the mouse over the link without clicking. The real destination shows in the bottom-left status bar of your browser or email client. On a phone, long-press the link to preview the URL.

  • Real Microsoft, PayPal, or bank links go to those exact domains, not redirects through unrelated sites
  • Shortened URLs (bit.ly, tinyurl, t.co) hide the real destination - never click them in unsolicited mail
  • The visible link text and the actual URL must match - mismatches are the single biggest phishing red flag
Pro tip

When in doubt, don't click the link. Open a new browser tab and type the company's address yourself, then log in normally. If there really is an issue with your account, you'll see it there.

4

Treat unexpected attachments as hostile

30 sec

If you didn't ask for the file, don't open it - even if it appears to come from someone you know. Categories that should never be opened from email without verification through another channel:

  • .exe, .scr, .iso, .img, .vbs, .bat - executables, never legitimate attachments
  • .docx, .xlsx, .pptx with "Enable macros" prompts - the macros run the malware
  • .pdf with "Click here to view" buttons - usually a phishing redirect, not a real document
  • .zip, .rar, .7z archives, especially password-protected ones - the password defeats the email scanner
Phase 2~ 2 min
Report and delete - if you haven't engaged

If you only received the email and didn't reply, click, or open anything, the steps below are all you need. Your computer is not infected.

5

Don't reply, don't click "unsubscribe"

30 sec

Replying confirms your address is real and monitored, which gets you added to higher-value scam lists. The "unsubscribe" link in a scam message is rarely a real opt-out - it usually leads to a phishing page or downloads a tracking pixel.

Instead, mark the message as junk or phishing inside your email client (this trains the spam filter), then block the sender.

6

Report the scam to your email provider and authorities

1 min

Inside your email client:

  • Gmail: open the message → ⋮ menu → Report phishing
  • Outlook / Outlook.com: ⋯ menu → ReportReport phishing
  • Apple Mail / iCloud: Move to Junk, then forward to reportphishing@apple.com

Forward or report to authorities:

  • International: forward to reportphishing@apwg.org
  • United States: ic3.gov (FBI)
  • United Kingdom: forward phishing emails to report@phishing.gov.uk (NCSC SERS); for financial loss report at reportfraud.police.uk (Report Fraud, the successor to Action Fraud; 0300 123 2040)
  • Canada: antifraudcentre.ca
  • Australia: scamwatch.gov.au
  • EU: your national CERT - find yours via the ENISA CSIRT map

After reporting, delete the email and empty the Trash folder so you don't accidentally open it later.

Phase 3~ 10–60 min
Recover - if you already engaged with the scam

Pick the step below that matches what you did. If multiple apply, work through them in the order they appear - the steps are arranged from lowest to highest risk.

7

You only clicked a link (didn't enter anything or download anything)

Scenario: clicked link only10 min

Close the page right away. Don't enter any information, even if the page looks legitimate.

  • Clear your browser cache and cookies for the last hour - Chrome/Edge: Ctrl+Shift+DelLast hour → check Cookies and Cached files
  • Run a quick scan with Combo Cleaner in case the page tried to drop a file silently (drive-by download)
  • Update your browser to the latest version - most drive-by exploits target outdated browsers
  • Watch for new browser pop-ups, redirects, or unfamiliar notifications over the next few days
Why this matters

Modern browsers block most drive-by attacks, but a single click on a phishing page can still be enough on an outdated browser or unpatched plugin. A quick scan catches anything that landed silently.

8

You opened an attachment or downloaded a file - run a full malware scan

Scenario: opened attachment⚠ Highest risk60–90 min

Opening an attachment is the most common path to actual infection. Treat the system as compromised until the scans below come back clean. Work through these sub-steps in order:

8.1Disconnect from the network

Unplug Ethernet and turn off Wi-Fi. If the attachment was an info-stealer or remote-access trojan, this stops it from sending data out or receiving commands. Keep the network off until you've booted into Safe Mode (next step) - you'll reconnect there briefly to download the scanners.

8.2Boot into Safe Mode with Networking, then download the scanners

Windows 11: Settings → System → Recovery → Advanced startup → Restart now → Troubleshoot → Advanced options → Startup Settings → Restart → press 5 or F5.

Windows 10: hold Shift, click Power → Restart → Troubleshoot → Advanced options → Startup Settings → Restart → press F5.

Once Safe Mode has loaded, turn Wi-Fi back on and download Combo Cleaner (used in 8.4) and Microsoft Safety Scanner (used in 8.5). Safe Mode loads only minimal drivers, so most malware can't auto-run while you're getting the tools. Save both installers to your Desktop.

8.3Run Microsoft Defender Offline

Reboot to normal Windows. Open Windows Security → Virus & threat protection → Scan options. Select Microsoft Defender Antivirus (offline scan) and click Scan now. The PC restarts into a stripped-down environment and scans the disk before Windows fully loads - this is what catches rootkits and bootkits.

Recommended antivirus
Combo Cleaner

VB100 certified. Includes anti-trojan, registry/persistence scanning, and anti-spyware in one pass. The 7-day free trial is available.

Download Combo Cleaner
8.4Run a full Combo Cleaner scan

Install Combo Cleaner and run a full system scan (not the quick scan). Let it complete fully, review what it found, and apply the recommended actions. Combo Cleaner will quarantine known trojans and remove their persistence in the registry.

8.5Run Microsoft Safety Scanner as a second-opinion scan

Download Microsoft Safety Scanner (MSERT.exe). The binary expires every 10 days, which means every download has the latest signatures. Run a full scan after Combo Cleaner to catch anything one engine alone might miss.

8.6Reset browsers and clear notification permissions

Many email-borne trojans drop adware that hijacks browsers. Reset each browser you use:

Chrome: chrome://settings/resetRestore settings to their original defaults. Then chrome://settings/content/notifications - remove unfamiliar sites.

Edge: edge://settings/reset. Then edge://settings/content/notifications.

Firefox: about:supportRefresh Firefox.

8.7Re-enable Defender, Tamper Protection, and update everything

Open Windows Security → Virus & threat protection → Manage settings and confirm Real-time protection, Cloud-delivered protection, and Tamper Protection are all on. Then run Settings → Windows Update → Check for updates and update browsers and applications.

Important

If the scans keep finding new threats on each run, or files reappear after deletion, you may have a deeper compromise that needs a clean Windows reinstall. See pcrisk's full manual malware removal guide for the extended procedure (Process Explorer, Autoruns, hosts file inspection).

9

You entered credentials on a fake login page

Scenario: shared password⚠ Act fast20 min

Assume the attacker has your password and is using it right now. Speed matters.

  1. Change the password from a different, known-clean device (your phone is fine if it's not infected). Don't reuse the old password anywhere else.
  2. Enable two-factor authentication if you haven't already. Prefer an authenticator app or hardware key over SMS.
  3. Sign out of all sessions - most platforms have a "sign out everywhere" option in security settings, which kicks the attacker out.
  4. Review recent activity - look for unfamiliar logins, new devices, forwarding rules, or app permissions. Remove anything you don't recognize.
  5. Check your other accounts - if you reused that password anywhere else, change it there too. Check your exposure at haveibeenpwned.com.
  6. Update security questions - the attacker may have seen the answers in your account profile.
Why email comes first

If you only have time to change one password, change your primary email password - it's the recovery hub for every other account. An attacker who controls your email can reset everything else.

10

You sent money or shared bank, card, or ID details

Scenario: financial loss⚠ Contact bank now30 min

Time is the single biggest factor in recovering money. Banks can sometimes recall a wire or reverse a card transaction within the first few hours.

  1. Call your bank or card issuer immediately. Use the number on the back of the card, not any number from the scam email. Ask them to freeze the card, reverse the transaction if possible, and flag the account for fraud monitoring.
  2. If you sent a wire transfer or used a money-transfer service (Western Union, MoneyGram, Zelle, Wise), call them directly and request a recall. Some can be reversed within minutes if reported fast.
  3. If you sent cryptocurrency or gift cards, recovery is unlikely - but report it anyway, since law enforcement tracks these patterns.
  4. File a police report. You'll need the report number for any insurance, bank, or credit-bureau claim. Save the report number.
  5. File with the right authority for your country:
  6. Set fraud alerts on all major credit bureaus if you shared any ID details. US: Equifax, Experian, TransUnion. UK: Experian, Equifax, TransUnion (Cifas Protective Registration is a stronger option).
  7. Save all evidence - the original email (with full headers), screenshots of the fake site, transaction records, any phone numbers or chat logs.

Final scan and startup-app check

15 min

Reconnect to the network and run one final full scan with Combo Cleaner, followed by a Windows Defender quick scan. Then open Task Manager (Ctrl + Shift + Esc) and switch to Startup apps - disable anything unfamiliar.

Make sure Windows, browsers, and any applications you use are fully up to date. The infection vector that worked on you once usually involves outdated software.

Monitor accounts and credit for 30 days

Most fraud follow-ups land in the first month. Until that window closes, keep watching:

  • Bank and card statements - daily for the first week, then weekly
  • Email - watch for password-reset confirmations or login alerts you didn't trigger
  • Credit report - US: free at annualcreditreport.com; UK: Experian, Equifax, TransUnion all have free tiers
  • Breach alerts - sign up at haveibeenpwned.com to be notified when your email appears in new leaks

If anything new appears in any of those, treat it as a continuing compromise: change passwords again, contact the bank again, and update the police report.

Important: If you didn't click anything, didn't reply, and didn't open any attachment, your computer is not infected - just delete the email and move on. If you opened an attachment or downloaded a file, run an automated scan with Combo Cleaner and Windows Defender and stop there. That path catches the vast majority of email-borne malware without the risk of breaking Windows by deleting the wrong file.
