Wow-BC Installer - False Positive for Trojan
« on: October 02, 2008, 05:44:13 PM »
Had my WoW-BC installer pop up with a positive for a trojan yesterday when the screensaver popped up - had been off my computer for days so don't know when the scanner started picking it up.  I saw the positive, and forced an update of the virus database.  Unfortunately it still came up positive.  Waited for the update this morning, and was still a false positive..

Here's the Virustotal:

The Installer is clean - and has been since it was downloaded back in Feb 2008 when I reinstalled Wow on my machine.  The file hasn't been modified since I downloaded it.

Did you submit the sample to avast for analysis as that is the only way it would come to their notice ?

If it is indeed a false positive and it seems so, see http://forum.avast.com/index.php?topic=34950.msg293451#msg293451, how to report it to avast! and what to do to exclude them until the problem is corrected.

You're welcome.

They are normally quite quick to correct when confirmed.
