I am aware that Fireswals adware scaanner etc. often reports trainer as malware. Usually it's an general alert, but in case of "TRAINER (PATCH #3 - 07.24.2009)" there is an specific alert for "Trojan.Win32.Buzus.cdcz" by Kaspersy as well as AVG Internet Security.
Would be very kind if someone could recheck this.
