Well this is close to my home thanks…
Sorry but one last question…
What if I want to sell avast as a reseller…?? And I don’t have a website…? Can I do reselling for avast?
http://www.avast.com/resellers
No minimum sales requirements (but must have IT/software-related company website)
Definitely a Scam… Can they do something about it? to report this URL or something?
Sure, they can block the site. 
You can report it here: virus[at]avast.com
you mean email them? cant someone on this forum do it? ( a moderator perhaps?)
I guess, someone already did…!
I just answered your question…
Ok thanks 
but here after to report a suspicious site/ potential virus I have to email them to that address or ?
Thanks for the info
Yep.
