What is "Doing Business With Your Company"?
Our team has reviewed this email and found that it is a phishing letter designed to trick unsuspecting recipients into entering personal information on a deceptive website. This email is disguised as a letter regarding a purchase that the sender intends to make. Recipients should ignore this email and leave its contents unopened.
More about the "Doing Business With Your Company" scam email
This phishing email is disguised as a business inquiry. The scammers behind it attempt to lure the recipients into clicking on misleading links. They falsely claim to offer product samples for potential business collaboration and direct recipients to log in with their company email and password.
Clicking the links ("View Our Sample", "Download", and others) included in this fraudulent email leads to a fake login page designed to steal entered information (login credentials). With stolen email account login credentials, scammers can access the email and then look for sensitive information, and send phishing emails or even malware to contacts.
Furthermore, they might attempt to access other accounts, such as social media or banking accounts, using the stolen login credentials. Therefore, recipients who fall for such scams can become victims of identity theft, suffer financial loss, and experience other issues. It is crucial to scrutinize suspicious emails thoroughly before divulging any personal information or clicking on links.

Similar scam emails in general
Usually, scammers behind phishing emails aim to trick recipients into believing they have received various types of important documents, such as invoices, shipment notifications, legal notices, etc. Also, they often use urgent language to trick users into opening the included links or files. The goal of such emails is to steal sensitive information.
However, such email can also be used to deliver malware. A couple of examples of similar emails are "Email Is Due For Validation", "DHL - Notice For Failed Package Delivery", and "WalletConnect Temporary Closure".
How do spam campaigns infect computers?
When cybercriminals use email to distribute malware, they send malicious files or links. The links in fraudulent emails can redirect users to malicious websites that host malware. Users might unintentionally download harmful files or programs, or the sites might automatically download malware onto their systems.
Users can also infect their computers through email by opening malicious attachments. Fraudulent emails may include attachments like MS Office and PDF documents, archives, executables, JavaScript files, and other formats. Malware infiltrates systems when users execute it by performing actions such as opening malicious executables or enabling macros in compromised MS Office documents.
How to avoid installation of malware?
Do not trust unexpected emails from unknown senders, especially when they contain files or links. Always examine emails before opening their contents. Download software from reputable sources like official pages or app stores (avoid using sources like P2P networks, unofficial sites, third-party downloaders, etc.).
Furthermore, do not interact with links, buttons, pop-ups, ads, etc., encountered on dubious websites, and do not allow websites of this kind to send you notifications. Keep the operating system (and installed programs) up to date. Additionally, install a reputable security tool and scan your computer regularly.
If you have already opened malicious attachments, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate infiltrated malware.

Instant automatic malware removal:
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"
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"
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"
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"
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"
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"
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"
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"
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)
How to spot a malicious email?
Check the sender's actual address, not the display name
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.comaddress - Reply-To mismatch - the From address looks legitimate but Reply-To points somewhere completely different
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.
Watch for urgency, threats, and generic greetings
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
Hover over every link before clicking
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
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.
Treat unexpected attachments as hostile
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,.pptxwith "Enable macros" prompts - the macros run the malware.pdfwith "Click here to view" buttons - usually a phishing redirect, not a real document.zip,.rar,.7zarchives, especially password-protected ones - the password defeats the email scanner
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.
Don't reply, don't click "unsubscribe"
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.
Report the scam to your email provider and authorities
Inside your email client:
- Gmail: open the message → ⋮ menu → Report phishing
- Outlook / Outlook.com: ⋯ menu → Report → Report phishing
- Apple Mail / iCloud: Move to Junk, then forward to
reportphishing@apple.com
Forward or report to authorities:
After reporting, delete the email and empty the Trash folder so you don't accidentally open it later.
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.
You only clicked a link (didn't enter anything or download anything)
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 - → Last 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
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.
You opened an attachment or downloaded a file - run a full malware scan
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:
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.
Windows 11: → 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.
Reboot to normal Windows. Open . 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.
VB100 certified. Includes anti-trojan, registry/persistence scanning, and anti-spyware in one pass. The 7-day free trial is available.
Download Combo CleanerInstall 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.
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.
Many email-borne trojans drop adware that hijacks browsers. Reset each browser you use:
Chrome: chrome://settings/reset → Restore settings to their original defaults. Then chrome://settings/content/notifications - remove unfamiliar sites.
Edge: edge://settings/reset. Then edge://settings/content/notifications.
Firefox: about:support → Refresh Firefox.
Open and confirm Real-time protection, Cloud-delivered protection, and Tamper Protection are all on. Then run and update browsers and applications.
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).
You entered credentials on a fake login page
Assume the attacker has your password and is using it right now. Speed matters.
- 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.
- Enable two-factor authentication if you haven't already. Prefer an authenticator app or hardware key over SMS.
- Sign out of all sessions - most platforms have a "sign out everywhere" option in security settings, which kicks the attacker out.
- Review recent activity - look for unfamiliar logins, new devices, forwarding rules, or app permissions. Remove anything you don't recognize.
- Check your other accounts - if you reused that password anywhere else, change it there too. Check your exposure at haveibeenpwned.com.
- Update security questions - the attacker may have seen the answers in your account profile.
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.
You sent money or shared bank, card, or ID details
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.
- 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.
- 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.
- If you sent cryptocurrency or gift cards, recovery is unlikely - but report it anyway, since law enforcement tracks these patterns.
- File a police report. You'll need the report number for any insurance, bank, or credit-bureau claim. Save the report number.
- File with the right authority for your country:
- US: ic3.gov + reportfraud.ftc.gov
- UK: reportfraud.police.uk (Report Fraud, the successor to Action Fraud; 0300 123 2040)
- Canada: antifraudcentre.ca
- Australia: scamwatch.gov.au
- EU: your national CERT or police cybercrime unit
- 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).
- 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
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.
Frequently Asked Questions (FAQ)
Why did I receive this email?
Scammers often distribute mass emails to numerous addresses, seeking to trick unsuspecting individuals into falling for their schemes.
I have provided my personal information when tricked by this email, what should I do?
If you have revealed credit card details or login credentials, contact your bank or the relevant service provider immediately. If you have given ID card details (or similar information) to scammers, report the incident to your local authorities.
I have downloaded and opened a file attached to this email, is my computer infected?
If the file was executable, it probably infected the system. If it was a document like a .pdf or .doc, you might have avoided infection since opening such files does not always instantly expose computers to malware.
I have read the email but did not open the attachment, is my computer infected?
Emails cannot cause direct harm. Computers become exposed to malware when recipients open malicious files or links.
Will Combo Cleaner remove malware infections that were present in email attachment?
Combo Cleaner is capable of detecting and removing most known malware infections. It is strongly recommended to run a full system scan to detect and remove advanced malware, as malware of this kind tends to hide deep in the system, and a quick scan is not enough to detect it.
