Hackers are developing websites that load Trojans onto end-users’ machines but delivered innocuous files to anti-virus companies. Other Trojans monitor firewalls and automatically click yes to alerts asking if the Trojan’s activity is permitted.Another technique is to wrap known viruses in multiple packets, known as packers, which hide the file from virus scanners. Kaspersky said that cybercriminals were modifying existing packers at a rapid rate to evade anti-virus signatures. The percentage of viruses that contain payloads which target anti-virus software is also growing.Full story: <a href="http://www.computerweekly.com/Articles/2007/01/19/221298/hackers-find-new-ways-to-beat-anti-virus-tools.htm" target="_blank">ComputerWeekly</a></blockquote>
