It may mean you've been looking at naughty website and picked up a worm /trojan/adware thingy .

You could try downloading and running Adaware or Hijackthis.............

or Pest Patrol they are all FREE..:

Sounds like you have a trojan m8....

Go to our site and download hijackthis, click on the link below, always remember to update your AVS and get a firewall. Better still use Firefox.... it doesn't affect Firefox!!!:p
