I have a google sight as my home page for every time Explorer opens. All of a sudden, now when I go to open my home page, my homepage comes up for a second and then automtically goes to an advertisement for an anti virus program. In my Control Panel my home page is still listed as normal. Now I have blinking icons on my task bar, when I click them on they go right to these anti virus sites automatically. It is as if someone got into my computer and has switched it, but I cannot switch it back. I tried going into Contol Panel to remove these, but I do not see any programs with there names on it. One icon takes me to a Spylocked site. How can I fix this?
