BlackGuard in general

Having a computer infected with BlackGuard stealer can result in financial (cryptocurrency) loss and other problems such as identity theft, loss of access to personal accounts, etc. Stolen clients may be used to send spam or even deliver malware. Examples of other information stealers are Gomorrah, Grakate, Phoenix.

How did BlackGuard infiltrate my computer?

Cybercriminals distribute malware using emails, cracked software download pages, Trojans, fake updaters, untrustworthy sources for downloading software and files. In all cases, computers get infected after a malicious file is executed. Emails used to trick recipients into downloading (and executing) malware contain malicious links or attachments.

Cracked software download pages often are used to distribute fake cracking tools or malicious installers. It is illegal and unsafe to use cracking tools or installers for pirated software. Examples of unreliable sources for downloading files (or programs) are unofficial pages, third-party downloaders, P2P networks, free file hosting sites.

Most cybercriminals attempt to trick users into downloading and executing malicious documents (for example, PDF, MS Office docs), JavaScript files, archives like ZIP, RAR (files in them), executables.

How to avoid installation of malware?

Download files and software from official pages and always use direct links. Do not open files (attachments) and links presented in irrelevant emails sent from suspicious/unknown addresses. Remember that most cybercriminals impersonate legitimate entities and disguise their letters as urgent/important.

Update and activate the installed software (and the operating system) using tools or functions provided by official developers. Use reliable antivirus software for computer protection. 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.

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.
