Hello, sometimes when working on the computer I see a popup message which says that Sophos has detected a threat and puts up a window where I can open quarantine manager. When I click on that the eooro message disappears and there is no trace any more of the error/warning. This makes me suspect that there is some sort of rootkit running that detects that the antivirus has detected it and then elimiantes all trace. Is this possible? How to know or do a ground-up re-test?
Another clue, maybe. Although properly installed (as far as I know) the Sophos Scans window says that the Scan Local Disks has "never been run" though I have run it many times and the Scan / shows last scanned on 5 May even though i have run it many times since....
