Avast needs to detect more adware. There needs to be web shield improvements to help detection. It was proven at www.youtube.com/mrizos
I am sure that the goal for avast from the alwil-guys is to be better and better, and to detect more and more stuff
Actually if you look at most reputable testing sites Avast detection rates are considered rather good.
mrizos’ youtube channel does offer some interesting thoughts, but hardly represents proof.
Always has been a problem running these sorts of tests, because there are thousands of new malware created almost on a daily basis. By the time a test has been compiled, performed, and released, the landscape has changed.
