I suggest submitting the problem files to
Virustotal.com. Virustotal will scan the files with ~30 top tier Anti-virus and Anti-spyware products and show you the results of each scanner. It is a very nice tool.
Here is the list of vendors that participate in VirusTotal:
* Aladdin (eSafe)
* ALWIL (Avast! Antivirus)
* Authentium (Command Antivirus)
* Avira (AntiVir)
* Cat Computer Services (Quick Heal)
* ClamAV (ClamWin)
* Computer Associates (Iris, Vet)
* Doctor Web, Ltd. (DrWeb)
* Eset Software (NOD32)
* ewido networks (ewido anti-malware)
* Fortinet (Fortinet)
* FRISK Software (F-Prot)
* Grisoft (AVG)
* Hacksoft (The Hacker)
* Ikarus Software (Ikarus)
* Kaspersky Lab (AVP)
* McAfee (VirusScan)
* Microsoft (Malware Protection)
* Norman (Norman Antivirus)
* Panda Software (Panda Platinum)
* Prevx (Prevx1)
* Softwin (BitDefender)
* Sophos (SAV)
* Sunbelt Software (Antivirus)
* Symantec (Norton Antivirus)
* UNA Corp (UNA)
* VirusBlokAda (VBA32)
* VirusBuster (VirusBuster)
If these vendors don't report the files are a problem and Stopzilla does, then I think the Stopzilla results are very suspect. There are a lot of "rogue" anti-spyware tools out there. Some even posing as legitimate tools. I have written an article on
spyware that you may find helpful.
Good luck!
