Yup!...
that has been a technique I've used for years, to flush out bad actors, and take advantage of Avast's good behavioral heuristics. However, I haven't needed this tactic for quite a while, because NT5 and NT6 under 64 bit protection, has made limited accounts practically invulnerable to viruses. Now malware that don't need special permissions to do their damage are the threat. A new order in detection, or in the case of Lavasoft's product - obfuscation - is in order. It is really sad that company went to the hogs(so to speak).
