The Forums are divided into sub-forums, related to the various avast products, this General forum is for things unrelated to the main products. There are also sub-forums for other languages.
Basically the link given by Asyn should go to the Avast Free Antivirus/Pro Antivirus/Internet Security/Premier, not for specific advice but to post your question in the correct forum.
Clicking the New Topic button at the top of the listings creates a topic in the correct sub-forum. I hope this is clearer as to what you should do.
