About a week ago when using IE8 on Windows XP, out of the blue, everytime I open a link a blank window pops up with the URL http://www.ilitili.com/sc?9 followed by 20-25 additional characters that are different each time this window opens. I have tried to get rid of it with my SYSTEM MECHANIC and SPYBOT with no success. I have gone to Internet Options and added this URL to the RESTRICTED SITES list with no success. HELP PLEASE. Thank you.
