Testing Anti Virus Software Against Packed Malware

Very interesting idea as packed malware is something rather common these days, and as we've seen the recent use of commercial packers in the "skype trojan" malware authors are definitely aware of the concept. What the authors did was to pack the following malware using 21 different packers/software protectors - Backdoor.Win32.BO_Installer, Email-Worm.Win32.Bagle, Email-Worm.Win32.Menger, Email-Worm.Win32.Naked, Email-Worm.Win32.Swen, Worm.Win32.AimVen, Trojan-PSW.Win32.Avisa, Trojan-Clicker.Win32.Getfound, and scan them with various anti virus software to measure which ones excel at detecting packed malware. What some vendors are best at detecting others doesn't have a clue about, but the more data to back up your personal experience, the better for your decision-making.
