However, since this is your first post and you are using a link in your signature that you appear to be linked to/connected with.
This is considered link spamming - not to mention you also have a listing on Stop Forum Spam, an entry for your email address. I suspect for the same thing probable link spamming.
I would suggest (if you are a genuine avast user) that you remove the link in your signature or other action is likely to occur.
