Do about what 
There first needs to be something that makes you vulnerable.
My thinking / wondering out loud angle is: If there are this many bugs with seemingly regular aspects, or as TrueIndian put it, "stability and other non-security related" areas of avast, why would it be incomprehensible to accept the possibility that there can be vulnerabilities hidden away in some deep areas of avast and that as of yet, no one from avast and no one who frequents tech forums has happened upon them?
Example #1: If say a software like Windows (ALL versions to date) could somehow be designed and developed to where now it was possible to make it be absolutely 100% SAFE today and from this point on, there would have never been the need for the perennial Update Tuesday. True, not all updates are to fix vulnerabilities, but many are.
Example #2: Say you have hired a contractor to build you a house. You periodically go check out their work progress. Say you see various cases of unsatisfactory workmanship in areas that are easily obvious. Wouldn't it make you wonder what workmanship is hidden behind the sheetrock in the walls and under the floor concrete, etc.? Just because we can't see a problem, it doesn't mean it isn't there.
Example #3: Say your vehicle had some serious issue that necessitated a recall campaign to fix it 2 years ago. Just because that was an "old" issue and was fixed by the recall, that does not mean there cannot be another serious issue pop up that requires another recall next month or next year or in 2 years. Maybe even various more issues necessitating recalls.
Anyway, don't worry. I like avast. I'm very happy with it.
We can't ignore though that it's been said on these very forums time and again, " No anti-virus can find ALL malware."
