Hello, I am running NIS 2012 and have found what seems to be a bug in the anti-virus quarantine process. I have had two files quarantined recently (bicyclecrazyeights.exe and isi launcher.exe). Both were quarantined by Auto Protect due to the WS.TROJAN.H virus. This is likely a false positive.
They were both quarantined and sent to Norton who "Exonerated" them later on and removed them from quarantine. It also put both files back where they came from. However, if you so much as open the directory where they are they are immediately sensed by Auto Protect and quarantined again.
It would seem that something is very wrong here.
