Welecome to the forum!
Ok avast is very good commercial and non commercial software. I think avast need better advertisement. Web page isnt nice. For example avast hasnt virus radar. Threatment radar and other labs. Dangerous level and other good think. Very nice page has symantec. Make something new.
Well, I prefer that they work with the programs, instead of the website, and in my humble opinon I like the website, it's clean, loading fast, and have nice colours. And I don't think avast would get more customers, just because they have virus radar, and such stuff.
When will be avast 5?
When it's ready!
Please search the forum, there is some threads about avast 5. It will problably come some time in the first six months next year according to Vlk.
