Today when I was doing a full system scan one file was reported being infected with a virus. The exact same file didn't trigger any alerts last week when it was scanned. I've had this file on my system for a long time and it comes from a reliable source which makes me think it's a false positive. Should also mention I have the same file in two different locations and it was reported in both these locations (and moved to quarantine).
Is there any way I can report this or have the file checked if it indeed contains anything harmful?
