I'm scanning my computer with TDS-3 and the program has found the RAT The Prayer 1.2 in Comodo\Firewall\CPF.exe
I would also quite confidently 'assume' this is a false positive.... and totally agree with ~cat~.... to do some other "outside" scans from programs possibly like Super AntiSpyware and possibly Trojan Hunter to see if something comes up.

BTW...I'm curious, when was the last time you were able to update the TDS-3 "trojan reference files"(.trf)?? I only ask because the program has been discontinued for some time.
