Hey!
Guess what??!!
SAV did not detect even a single virus on my PC!! That means Avast did not let any virus into my PC! I'm impressed!
So its bye bye SAV and welcome back Avast!
(This switch lasted not even an hour!!)

I think this way is not a good methodlogy to judge a quality of an AV. Because there's NO AV finds everything, sometimes Avast misses some malware that Norton, McAfee, Trend Micro, Kaspersky, AVG, NOD32 find but sometimes it will be vice versa. But when it comes to major malware or ITW malware so every AVs will find it all as soon as possible.
The company I used to work uses several AV products from several vendors, e.g. Fortinet Antivirus Firewall at perimeter, GFI product at mail server (GFI uses several engine such as Kaspersky, BitDefender, Norman) and Trend Micro at file server and desktop. My experience has been that each scanner will occasionally catch malware that one or others miss.
I use and trust Avast but I've always used other scanners for scanning my pc from time to time, sometimes it come up with nothing but sometimes it come up with malware files from browser cache (just the files that get through Avast real-time scanner but my pc is not get infected and I never get infected when using Avast) that Avast misses. One thing I've noticed that Avast always cause false positive from time to time even it has no heuristics.
But above all, Avast runs sweetly and beautifully on my machine with good protection, that's all.
