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. When will be avast 5? No only program little update.
Welecome to the forum! 
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 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.
I think too but avast skin need be better and avast web page too. Avast has protection of viruses Kriptik and Gimmiv.A?
From version 5 there will be no skins.
In the mean time there are more skins than you can shake a stick at, click the get more link, see image.
I have already answered your question about virus names in one of the other posts you made about this.
