    I was unpacking some Rar files using WinRar (shareware)  downloaded from cnet.com a couple of hours ago.

    After unpacking, I uninstalled WinRar through Add/Remove Programs from the Control Panel and guess what? AVG (v6.0.346) alerted me that there was a virus named 'Hidden extension.bat'. No details of this 'virus' was available from AVG control panel.

    I managed to trace the concerned file to C:\Documents and Settings\Administrator\Local Settings\Temp\Uninstaller.Rar and removed it manually. After which I re-ran AVG again and the result was clean.

    Prior to the manual removal process I ran NAV2002 but it detected nothing.

    Did AVG mis-identified the file as a virus? Any opinion(s) would be appreciated. Thanks

    Hi WE Sim,

    Always nice having you around!

    Since there's obviously no file left anymore to check, it's impossible to state anything with full certainty.

    That said, looking at the description you posted, I tend to believe (well, a bit more than that, but anyway), this has been a false positive; "hidden extension.bat" probably triggered it.

    Nevertheless, I full deep scan with a good and updated anti-trojan would be recommended, to be on the sure side.
