Hi board I have tested many antimalware scanners : AV, AT, AS etc. against very well known and easily detectable malware but encrypted with Themida runtime packer, all of them have failed except Avira AntVir in all encrypted malwares and Pest Patrol in some of the encrypted malwares. Specifically I have tested these AV's : KAV, NOD32, BitDefender, Pc-Cillin, Norton, AVG, Avast. And these AT's and AS's : AVG (Ewido), T Hunter, T Remover, SpySweeper, SpywareDoctor, SAS, Ad-Aware Pro, SpyBot, A2, TMAS. Note : I tested every scanner with a Themida encrypted malware wich is easily detectable by the same scanner when it was not encrypted !! No one succeeded except Antivir all the time, and Pest Patrol some times, all other failed every time . It is a very annoying test result which means that any trivial but Themida encrypted malware can easily infect a machine protected by any first class AV or AT or AS but AntiVir ! Now I cann't feel safe any more without AntVir. Did you try any other scanner against Themida encrypted malware? If not please do and share your results with us.
