My dad's computer has got "Antivirus IS" on it, fucking pain in the arse. Thought I'd got rid of it and its back again.
Strange thing is that it's only affected his user account, the others on his computer aren't infected. Never seen that before.
As I don't use Windows much, can someone recommend the best way of stopping it from getting on there again?
Don't mind paying as it will save me the time and hassle of removing it next time.
I used to remove certain things manually before cleaning with malwarebytes etc using Eraser. I'd first check start up entires in msconfig for the exe/s, then restart in safemode, kill the process if running, and then Erase all instances of the exe and remove all mentions of it from the registry. Then I'd restart and run the various programs. It's pretty basic, but it often managed to get around the worst of it, unless the exe was actually an infected system file.
