Yeah, I'm a victim of Avast, too. I did a full scan last night after installing the newest version of Avast, and it deleted some stuff. And since I was scanning my backup drive "just to be safe" I've lost some things that I can't get back. 
I just renewed yesterday, too. I doubt I can get a refund, so I guess I'm out the $35 because I'm going to switch anti-virus software.
Why you deleted those files? Avast by self don't delete anything. And if yes by system file shield, it will be in your virus chest = easy restore. You are only victim by self.
First off the files were/are in my virus chest, but Avast doesn't restore them when I try to do so. I claims it does, but the files are still MIA. But I'm sure you will say that's my fault.
Secondly, I wouldn't have installed a new version of Avast if tech support would have responded to the ticket I opened about renewing Avast 11 days ago, before my Anti-virus ran out. But I'm sure you will say that's my fault.
Thirdly I did a full scan on my PC because I had no foreknowledge that Avast was malfunctioning, and acting as malware. No if Avast had sent out one of those so called alerts that they send out whenever they are trying to sell some sort of upgrade or add-on then maybe I would have been warned in time and not ran the virus scanner. And to date Avast STILL hasn't warned anybody. But I'm sure you will say that's my fault.
Lastly,and most importantly, I pressed the button to resolve what my anti virus program reported as malware, because I trusted that my antivirus program was doing it's job and detected malware. That the whole point of buying antivirus and anti-malware protection. Becuase otherwise how would we know when our devices were infected ? Should we all Wait until we start to notice performance issues? Should we run some other sort of antivirus protection? And if so, then why pay for Avast? If we have to second guess our AV protection then what good is it?
Oh, and ignoring my issues for a minute. What about the people who still aren't aware of the problem who might have files or have it in their virus chest now? Those files are still tagged as infected, and unless those people happen to stop here they won't be aware of it. And what about what happens now? If any of us see a lot of files tagged with VBS tomorrow, will we just assume it is a bug in Avast and ignore it? That could really be opening up a can of worms.
Now you want to put this all on the head of those of us who Pressed the button then fine. But then, you aren't the one paying for Avast or trying to sell it.
