So as the malware war continues, I have found that the fake AV virus learned a new trick or two. The latest version I dealt with had a new rootkit in it that prevented combofix, malwarebytes and superantispyware from running. Of course it is not smart enough to stop those pieces of software from running if you change the name of their executables.
I suggest using combofix from bleepingcomputers.com first. Download it, rename the executable to comboxif.exe, and do not have it update. The autoupdate will have problems because of the infection. Just download the latest one available and run it.
Once combofix has run, all the other anti-malware programs should run without any issues or needing to rename them.
I tried at least a half-dozen applications to get a executable virus off my PC. One even required me to restore my computer. All the spyware/malware/virus programs found a quarantined the problem, but never removed it. This application found AND FIXED the problem.
