Hope this helps.
I recently encountered a virus on my computer called Antivirus Action. It pretended to be a security software, that looked very similar to windows. I rebooted in safe mode with networking, I went into Task Manager and deleted any processes I thought unnecessary. I then went into start, ran regedit, and went through the steps as shown on the link below;
I only found one file hidden that as named 'Antivirus Action' and deleted that. In the video it said there were several.
I rebooted in normal mode and now the computer is working fine. However i'm afraid that maybe the virus is under a different name.
Any ideas would be much appreciated
