Malspam campaigns in general

Most cybercriminals behind malicious emails pretend to be legitimate companies or other entities. They achieve their goal when users open a malicious file. A couple of examples of other malspam campaigns are "INTERLINK Email Virus", "Erweka Email Virus", and "Baldur Email Virus".

How did ANSR email virus infect my computer?

Recipients infect computers by opening a malicious VBS script downloaded through a hyperlink provided in this email. A couple of examples of other that can be used to deliver malware are PDF or MS Office documents, archive files, executable files.

Malicious documents opened with MS Office 2010 and later versions do not infect computers unless users enable macros commands (or editing, content). Documents opened with older MS Office versions infect computers instantly. It is because those versions do not include the "Protected View" mode.

How to avoid installation of malware?

Avoid opening files and website links in irrelevant emails sent from unknown, suspicious addresses. Use official websites and direct links to download files or programs. Updated and activate the software with tools provided by its official developer.

Scan the operating system for threats regularly. Run scans with reputable security software and keep it up to date. If you've already opened "ANSR email virus" attachment, 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.
