I think i have a virus,?

Sounds like you have allot of spy ware running on your computer. You need to run anti spy ware and update it. also delete all your cookies. you should run that along with your anti virus at least once a day and update it ever two to three days at most. download AVG anti virus and spy ware and Search and destroy spy ware. you can find them both at www.download.com. I've been using them for years. AVG is very good and finding most. Also you may want to install a software firewall. If you have a router it has a hardware firewall already built into it. Not good enough, you need to run a software one as well. Zonealarm is a very good one and these are all free.
