Your machine is infected. Pop-ups are mostly caused by adware, spyware, and other malicious and unwanted software and using pop-up blocker won't help an infected PC. In addition to McAfee (your anti-virus) you need anti-spyware.

No single program can detect and eradicate all spyware and I recommend using Ad-aware and Spybot (they are free). Other great free anti-spyware programs would be Super anti-spyware and AVG anti-spyware (formally Ewido).

Running these programs in Safe Mode (tap F8 as the computer boots up and choose to boot to safe mode) can be more effective.

I strongly recommend using FireFox, it's a far better and safer alternative to Internet Explorer. If you add-on McAfee SiteAdvisor, it will warn you of potentially harmful sites. I also recommend CCleaner which is a free system optimization and privacy tool.
