Answer 1

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. No single anti-spyware application is perfect so I recommend using at least 2 different programs. Spybot Search & Destroy is one of the best. I also recommend SUPERAntiSpyware. Other free anti-spyware programs would be Adaware, AVG Anti-spyware (formally Ewido), A-squared, Spyware Terminator and SpywareBlaster.

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

If you do not have an updated anti-virus program always running, you need to get one. Install only one, but you can get AVG, Avast! or AntiVir for free.

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.
