Malware of this type in general

Typically, malware like PseudoManuscrypt is used to steal as much sensitive information (such as credit card details, login credentials) as possible. Cybercriminals use it to steal identities, banking and other accounts, and for other purposes. More examples of malware with similar capabilities are FlawedGrace, Bloody Stealer, SHurk Steal.

How did PseudoManuscrypt infiltrate my computer?

As our team has found out, one of the malicious installers used to distribute PseudoManuscrypt is a fake pirated installer for SolarWinds. Although, there can be other fake installers distributing this malware too. It is important to mention that it is against the law to use pirated software.

Examples of other channels used by cybercriminals as tools to distribute malware are malicious emails, untrustworthy sources for downloading files/programs, Trojans, fake updaters (and installers). As a rule, computers get infected when users execute malware by themselves.

How to avoid installation of malware?

Use official websites and direct links as sources for downloading files and software. Other sources can be used to distribute malware. Remember that opening attachments and website links in irrelevant emails sent from suspicious or unknown addresses can cause computer infections. Thus, carefully examine emails before opening their contents.

Always use official tools (or functions) provided by official software developers to update and activate any installed software (and the operating system). If you believe that your computer is already infected, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate infiltrated malware.

After you locate the suspicious program you wish to remove, right click your mouse over its name and choose "Delete".

Delete malware in Autoruns

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.

Search for malware and delete 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 Combo Cleaner Antivirus for Windows.
