How can you remove virus but your antivirus not detect?

Answer 1

You have to look for it, any files that look like they shouldn't belong you might want to delete. It can really be hidden anywhere, but the most common places are the Temp folder, System32, and the Windows folder. Check your Temp folder (Start> Run > %temp%), sometimes a virus can be sitting there in plain sight. Try not to delete the System32 folder though ;).

Answer 2

if you want to remove a virus go on full system scan and go on scan detials and where it says disinfect and quarentine go on the drop down window and click remove... i hope this helped
