Why do you offer files that contain viruses and trojans?

We never ever intentionally distribute viruses, trojans or any form of malware. Unfortunately modern virus scanning software using their default setups employ a scan and detection technique known as heuristic scanning. In addition to the standard scanning for malware code using a black-list heuristic scanning looks at the program for malware like behaviour. Many scene intros and crack-tros implement self decrypting and decompressing techniques which unfortunately is common behaviour for malware that is attempting to infect your system.

Scanning for behaviour is never going to be 100% accurate and an oversensitive heuristic scan can report what are known as false positives. Where a scan has incorrectly claimed there is a potential threat but cannot pinpoint what that threat is and instead gives it a generic name.

This is why some files offered on Defacto2 are listed as potential virus or trojan threats. We do not believe they are infected with anything dangerous but some virus scanners are reporting otherwise.
