Spyware scan hits on a trojan named Win32.autorun . It will Quarantine it but after a reboot it will hit on the same thing again .I researched the internet and have found a few trojans named win32.autorun but they all look like this (
or some other letters after the autorun.Mine does not .I have Spy Hunter Security Suit 3 also installed and ran it after I did a reboot and they could not find anything .Spy Hunter scans the registery also
and in all the
win32.autorun trojan posts that I have read this thing is in the registry.
Is this a false positive message from Zonealarm or is this a real trojan ? And if yes what do I need to do to get rid of it for good ?thank you for any help
