Well, look at it this way. What do you think would happen to any AV vendor if it was determined that they were distributing viruses in their product?
Firstly, the government would shut them down.
Secondly, the lawsuits would ruin them for good.
Thirdly, there could be criminal penalties.
Fourth, it would tend to tick me off.

No responsible vendor would do such a thing. Are there irresponsible vendors? No, not really.....just less capable. AV vendors are fighting for a customer base and it certainly would not help them to even have such a "tint" of an accusation directed at them.
I do believe that in the "race" to keep up with competition, shody products are released before they are ready.
Avast is truly in a league by itself. The Avast team is careful at what it does and does the best it can before a release to have it bug free. From the very first time I used Avast, I knew if was different and special. I have not only been a long time user, but have spent many many hours on this Forum helping others get to know Avast. The time has been well worth it.
The success of this Forum is proof of the product. More users come here to laud Avast (praise) then I have seen on other AV forums.
Long live Avast!! and praise to all the Avast Team.
