I’m seeing a lot of searches for how to remove the rogue antivirus green AV. It looks like it’s the latest flavor of the minute in the rogue security application crowd. My usual path for removing a rogue antivirus or antispyware application is the same as any other malware, try to get other malware removal software on the system (such as malware bytes antimalware or super antispyware, AVG, spybot etc.) and get them running scans to eliminate it. (Make sure to get updates for the software first.) (Virus Removal Toolkit for links.) If that approach doesn’t get you anywhere then it’s time to find the name of the program file that’s running. It appears that with Green AV to remove it from the running processes you need to kill of the process called gav.exe. You may need to reboot into safe mode, then you can rename (or just delete) the offending program executable…. here’s a suggestion for you.
