Hi Eddy,
I provide a free Website Link service on my PR websites. This usually costs $2 - $299 (Magenet and Backlinks dot com)per month but I offer it free. So my popunders and popups views are only way to pay for my hosting and save a little. Even with this users flock to post their link; atleast 150-300 posts everyday.
I understand the iframe (to increase my visitor count) was detected as malware. I have removed them. Now how do I get the next update to clear this website from Avast Malware reports?
