I finally resolved an annoying series of “Win32:Trojan-gen {Other}” thanks to DavidR’s tip about Symantec live update applications: http://forum.avast.com/index.php?topic=36812.0
Instances of the “Win32:Trojan-gen {Other}” occurred in several locations (Program Files & System Restore), but in all cases, the offending files seemed to originate from Symantec (file names included SymLT.MSI, SymLCSVC, etc.)
I had eliminated Norton Antivirus a very long time ago, using Norton’s Removal Tool. However, I totally forgot that I still had an old copy of Norton Ghost on my computer.
Following DavidR’s advice, I checked in C:\Documents and Settings\All Users\Application Data\Symantec\LiveUpdate, & I found the LiveUpdate culprit. (Those sneaky so-and-so’s!)
I uninstalled Norton Ghost, then scoured my computer for any possible remnants, which I deleted.
Once that was taken care of, I disabled System Restore, then rebooted (purging old System Restore points), and voila: No more Symantec c**p!
But I still have a question:
I’ve run plenty of Avast scans, but these Symantec-based “Win32:Trojan-gen {Other}” warnings never occurred until fairly recently. Why is that?
Had the Symantec LiveUpdates changed in some nefarious way, or has Avast only recently begun to identify them?
Just wondering…
