I don't know what kind of curiosity leads people to the dark corners of the internet, when they want to obtain a new version of antivirus software. It's somehow irrational to find security software at insecure places. But.... it happens.
As you can see, the file name is Avast_Antivirus_2012_Trial_Verion.exe - but it is definitely not a proper setup released by us. Here are some facts, that are worth remembering:
we don't distribute new versions through grayzone portals. The best way to download recent version is to visit www.avast.com
our original setup package is properly signed with a valid certificate
our original setup has a typical "a" icon
The mentioned file from FP submission was not downloaded from the official source. It has no digital signature and no icon. In fact, it is a dangerous bootkit dropper - Sirefef/ZeroAccess - which no one really wants to have.
