"Email Quarantine" scam email removal guide
What is the "Email Quarantine" email letter?
"Email Quarantine" refers to a phishing email spam campaign. The term "spam campaign" is used to define a mass-scale operation, during which thousands of deceptive emails are sent. The letters distributed through the "Email Quarantine" campaign claim that users have several incoming emails, which have been "quarantined" (i.e. did not reach the inbox). To prevent the nonexistent letters from being deleted, recipients are instructed to log-in to their mail account. This is the main goal of this scam - to get users to inadvertently reveal their email account log-in credentials by entering them into a phishing website.
The "Email Quarantine" letters state that users have a specific number of emails in quarantine (as opposed to in the inbox or certain subfolder in the inbox). The title/subject of the researched variant was "You have (4) Messages Pending Delivery On Your e-Mail Portal", which implies that there are four "quarantined" emails. However, in the body of the letter it is stated that in fact two emails have been held back. The message is phrased in a way that implies users have a choice of how to approach the fake emails (i.e. release - allow into the inbox, delete, approve or block mail from the sender). To further the sense of urgency, the "Email Quarantine" scam letters claim that the withheld emails will be deleted within 24 hours (implying that users must take action immediately). The subjects/titles of the nonexistent emails (i.e. "AW: new order - V3088514" and "Fwd: Payment Advice Note from 06.11.2020") are also intended to sound important, thereby increasing users' hastiness. To prevent the imaginary emails from being deleted, users are to click the "Log in" button and re-access their mail account. This button redirects to a phishing site, which is disguised as a sign-in/log-in page. The webpage states that the session has been terminated and users must sign-in again to continue. It must be emphasized that all of the information provided by the "Email Quarantine" emails is false and by attempting to log-in through the phishing page - users will unintentionally reveal their log-in credentials to the scammers behind this spam campaign. Scammers target mail accounts as they are typically connected with other accounts; hence, through stolen email accounts - they may gain access to associated ones. Accounts of interest include (but are not limited to): social networking, social media, messaging platform, data storage and sharing, e-commerce, online money transferring, digital wallet, banking, and so forth. To summarize, trusting the "Email Quarantine" scam letters can result in loss of email accounts and others linked with them, severe privacy issues, financial losses and even identity theft. If attempts to sign-in through the phishing website have already been made, it is strongly advised to change the passwords of all potentially compromised accounts. Additionally, it is recommended to contact and inform the official support of all endangered accounts.

"Wire Transfer", "POWERBALL OFFICIAL 2020 WINNINGS", "Your Microsoft subscription has been expired" and "Last Warning: Upgrade your email to avoid Shutting Down" are some examples of other phishing spam campaigns. Phishing schemes do not exclusively target emails, but other accounts and personal information as well. Spam campaigns can have a variety of purposes and disguises. What is more, deceptive emails are also commonly used to proliferate malware (e.g. trojans, ransomware, cryptominers, etc.). Due to the relative prevalence of scam mail, it is advised to exercise caution with incoming emails.
How do spam campaigns infect computers?
How to avoid installation of malware?
To avoid infecting devices with malicious software proliferated through spam mail, it is advised not to open suspicious and/or irrelevant emails - especially any links or attachments present in them. Additionally, it is recommended to use Microsoft Office versions released after 2010. However, malware is also often spread via untrustworthy download channels (e.g. unofficial and free file-hosting websites, Peer-to-Peer sharing networks and other third party downloaders), illegal activation tools ("cracks") and fake updaters. Therefore, it is important to download from official/verified sources and activate/update programs with tools/functions provided by legitimate developers. To protect device and user safety, it is crucial to have a reputable anti-virus/anti-spyware installed and kept updated. Furthermore, this software is to be used to run regular system scans and to remove detected/potential threats. If you've already opened malicious attachments, we recommend running a scan with Malwarebytes for Windows to automatically eliminate infiltrated malware.

Extract the downloaded archive and run the Autoruns.exe file.
In the Autoruns application, click "Options" at the top and uncheck "Hide Empty Locations" and "Hide Windows Entries" options. After this procedure, click the "Refresh" icon.
Check the list provided by the Autoruns application and locate the malware file that you want to eliminate.
You should write down its full path and name. Note that some malware hides process names under legitimate Windows process names. At this stage, it is very important to avoid removing system files. After you locate the suspicious program you wish to remove, right click your mouse over its name and choose "Delete".
After removing the malware through the Autoruns application (this ensures that the malware will not run automatically on the next system startup), you should search for the malware name on your computer. Be sure to enable hidden files and folders before proceeding. If you find the filename of the malware, be sure to remove it.
Reboot your computer in normal mode. Following these steps should remove any malware from your computer. Note that manual threat removal requires advanced computer skills. If you do not have these skills, leave malware removal to antivirus and anti-malware programs. These steps might not work with advanced malware infections. As always it is best to prevent infection than try to remove malware later. To keep your computer safe, install the latest operating system updates and use antivirus software.
To be sure your computer is free of malware infections, we recommend scanning it with Malwarebytes for Windows.
