Today I testet the 'Norman Malware Cleaner':
http://download.norman.no/public/Norman_Malware_Cleaner.exe
The scanner told me, that it found Vundo in Portable Pidgin:
X:\PortableApps\PidginPortable\App\GTK\lib\gtk-2.0\2.10.0\engines\libthinice.dll
So I decided to double-check the file with:
http://www.virustotal.com/
http://www.virscan.org/
http://virusscan.jotti.org/
Unfortunately three other scanners found suspicious code in this file. I'm now pretty uncertain about this - ok, I won't even care about one false positive, but four?
