Clever malware can block your access to Windows’ Task Manager and Registry Editor, making it difficult to disable and delete the infection.
Several free tools, however, can help you root out these pesky Trojans and viruses — and prevent them from returning.
Battling the ‘Advanced Virus Remover’ Trojan
Peter Klugherz encountered sophisticated malware that just wouldn’t let go of his son’s PC:
- “My son called me for help last night because his computer has become infected with the Trojan Advanced Virus Remover (pavrm.exe). Among other things, pavrm.exe blocks access to Task Manager. Norton Internet Security detects it but apparently cannot remove it.
“Similarly, I can’t find any reliable information on the Web on how to remove it. When I search the Web, many sites recommend the purchase of their own anti-malware software. Do you know of any way to get rid of this software?”
As Peter discovered, if you try to remove the Advanced Virus Remover, you find that your access to Task Manager and the Registry Editor (Regedit) are blocked, making removal of this malware harder than normal. But there are several approaches to rid your system of this and similar kinds of malware. Even if you don’t encounter this specific Trojan, the same techniques can work whenever a similar problem occurs.
The first and perhaps most-obvious step is to use one or more of the many free malware-removal tools that find and delete this Trojan. From user reviews online, two that do the job are Malwarebytes’ Anti-Malware (which is available from the Malwarebytes’ site) and SuperAntiSpyware (from the vendor’s site).
