i clicked on a /bestfriends.scr link which contained a virus and now my internet is really slow. It takes a long time for me to sign onto AIM and my Internet Explorer isn't working well either. When I try to access a website through IE, I often get the "The page cannot be displayed" error page. I have to click refresh a dozen times or more to access the page. Sometimes I can access a site without trouble, other times it takes a dozen clicks. Sometimes I even get a "Cannot open search page" error message. Also, I have been getting several pop-up ads from offeroptimizer.com.
I've tried running McAfee AV scan but can't pinpoint the virus. Each time I turn on my computer, I get a McAfee alert telling me the trojan Qhosts.apd was detected and deleted.
Please let me know what I need to do to fix my computer. I've tried the Ad-Awares and Spybots and AV programs but nothing seems to be working. Thanks.
