I sent several requests and virus samples inside a .zip file with password to virus at avast dot com, few weeks ago, but avast pro and home seems uncapable to detect the "W32.Besso" and some viruses named "kavo" but looks like a Besso's variant.
I'm really concerned about this because I can't understand why a great antivirus like avast is still unable to detect and block infections from these virus and variants, since several months ago.
I don't know if this is a configuration problem, but now I need help with this... I had several customers infected with those virus and avast, which I recommended a lot, is just fully updated but the virus and variants are affecting many systems, infecting even iPods disks.
I hope posting to this forum will help to solve this issue, and really want to trust 110% in avast, as always.
I'm unable to attach here a virus sample.
Another virus not detected is the Trojan.PWS.Wsgame.3605
