I just received a virus warning regarding a Kprobe setup file - version 2.5 (kp2setup250.exe). I submitted it to virustotal.com and only two of the AV programs reported positive results. Jotti.org listed only Avast as finding a trojan.
Avast 4.7.844.0 Win32:Trojano-018
Ikarus 0.2.65.0 Trojan.Win32.StartPage.aak
