Hi, I was wondering if anyone knows how to solve the following problem: my computer has a virus that involves a pop up voice that says "congratulations you have won a walmart giftcard." i also keep getting random popups for websites, even when i have no other programs running. I have run spy bot multiple times, as well as a full symantic scan, but it keeps happening. any ideas or links on how to fix this? will i need to get my computer wiped? thanks a lot!
