I am running an HP Pavilion PCXT959 with MS XP and service pack 3. Yesterday, popups galore turned up from Antivir Solutions Pro telling me my PC was infected and that I could purchase a remedy from its Web page. My attempts to remedy the problem were blocked by Antivir, and I could not find the Antivir program in the program list when I right clicked the Start button or using search.
Download AntiMalware from www.malwarebytes.org (the free version). Boot into "Safe Mode with networking" and then install and run the malwarebytes application. Do a full scan and follow the recommendation for removal. You may need to also repeat this same process with combofix.exe, which can be downloaded from www.bleepingcomputer.com/combofix/how-to-use-combofix. Read and follow the instructions there.
The new strain of virus has been popping up in almost epidemic numbers lately by exploiting vulnerabilities in Windows (bypassing any installed antivirus) and Internet Explorer, as well as other programs as detailed in Microsoft Security Advisory 2286198 (www.microsoft.com/technet/security/advisory/2286198.mspx).
Make sure you are running a fully updated Windows and a fully updated Internet Explorer 8.0 in Protect mode with security set to a minimum of Medium-High. For Vista and Windows 7, make sure you are running under an account with normal privileges, which means do not turn off the User Account Controls (UAC).
My home computer is not hooked up to the Internet, but I apparently brought home a virus on a disc. Any good programs I could download on a CD and kill it? I'm running Vista.
From an Internet connected computer, locate and then burn to CD these two programs:
AntiMalware from www.malwarebytes.org and Combofix.exe from www.bleepingcomputer.com/combofix/how-to-use-combofix. These programs are free, so only click on the free offerings download links. On the infected PC, install and run the AntiMalware program first and follow all removal recommendations. If problems persist, move on to the ComboFix program. Go slowly and carefully.
