ClamWin Free Antivirus :: View topic - False positive or actual trojanin Pantech WAN card software?

Posted: Wed Feb 13, 2008 9:17 pm

I scanned programs in memory, and was told that the service utility for my WAN card (which has been installed and updated from my wireless provider over the air) had a trojan (Mybot-8199).

I'm wondering whether this is a false positive. What should I do to figure out which it is?

Here is the scan log:

Most likely it's a false positive if you've had/used the file/program for a time. Upload the file (if you can) to Jotti at https://virusscan.jotti.org/ on line, and they will provide a free scan of it with 20 antiviruses including ClamAV. If at least four or five antiviruses find malware, it is probably for real, and, in that case, contact the vendor before you do anything.

I recently had a ClamWin false positive for another antivirus program! FPs happen with all AVs from time to time. Viruses do many of the same things that normal software does--upload, download, change the registry, etc. That's why I configure ClamWin to Report only and not to quarantine--I don't want it to quarantine an important system file and lose access to the system.

Thanks for the link. It does appear to be a false positive.

You can report false positives to ClamAV at https://cgi.clamav.net/sendvirus.cgi on the Web. They will update the ClamAV virus signatures that ClamWin also uses, and you will be helping to improve the product(s).
