TSGL: Avast Virus Scanner and Avira Antivirus

[Alan Mitchell]

Many AV programs don't play well together. That's why few people run more than one. Why? Suppose AV program A has the "signatures" of various malware embedded within the program. AV program B scans and finds these signatures. So it does what it is programmed to do...notify you. What gets really interesting is when one program automatically puts the other in quarrentine which prevents you from using OR uninstalling the quarrentined program. I've had at least one case where I had to reformat a client's drive to resolve the conflict.

I think it's interesting to note that googling the malware gets no hits from Symantec, McAfee, CA, or any of the major AV programs.

Subject: TSGL: Avast Virus Scanner and Avira Antivirus

I have installed a couple free programs that I have never used before, but both come highly rated, so I have been trying them out.  These are Avira Antivirus Personal Scanner and Alwil's Avast Virus Scanner.  The Avira scanner keeps identifying Alwil Software (Avast) as the Trojan Horse TR/Gorshok.A
AVG Free does not identify it as a trojan.

I believe the Avira scanner is legitimate and downloaded from a legitimate site, but not sure why it keeps identifying Avast as containing a trojan, unless these two av's just won't play well together, and the result from Avira could just be a false positive.

This alert pops up a couple times each day.  I have Googled to read about this trojan, but everything is in a foreign language.  

I tried the Secunia Inspector online scan, but it's primarily looking for insecure software versions and missing updates instead of looking for Trojans.

What is a good safe website to help identify the trojan TR/Gorshok.A, and perhaps do an online scan to see if somehow it was installed with my download?  I tried the WindowsSecurity site, but it can't yet handle Vista.  I would like to specifically scan for Trojans, not just another typical virus scan.  And I'm not particularly fond of downloading yet another free virus scanner for a trial.  So, again, is there any reliable safe site for either identifying this virus and/or doing an online scan to see if I have it?
