Like the other two have said, use safe-mode to temporarily disable any viruses. This should allow you to go and find anti-virus software without being hindered by spam popups. I'd also recommend unplugging yourself from the Internet until it's dealt with (obviously you'll need it to download anti-virus)- just in case.
If you don't want to download anti-virus stuff, just use another computer and thumb drive it. That's what I did in my situation. Usually, the only way you can get something onto your computer when a virus is there is to use a thumb drive and not use the internet on that computer.
