I'm at my friends house and he uses AO-Hell, theres pop up messages(not actual ads), it says there is a leaking port in the computer and a big security threat blah blah blah...I was thinking its just advertisement because of it leaving a link to the site where you can download "block messanger". Since hacking into other computers is illegal i really doubt that anyone with much intelligence would leave a link to their site, but thats just my opinion, let me know.
