Like EEG, I always use Firefox, and I never have any popup problems. I think that Firefox is much better than Internet Explorer, and you also get less problems with spyware and malware.
Some of the popups can occur when viewing photographs on the forum because these are are stored on hosting web sites.
Along with the software that Kes has suggested run the following on a regular basis ...
Spybot - Search and Destroy from ....

http://www.ccleaner.com/ this will clean out any "debris" from the Computer registry (some of which can be hiding spyware, trojans etc.)
Whatsrunning from ......
http://www.whatsrunning.net/whatsrunning/download.aspx - this will show all programs and processes that are running on your PC. It also shows all of the programs that load when you switch the PC on and some of these are unnecessary and can be disabled.
If your PC is slow to startup or to shutdown it is almost certain that you have spyware or unwanted programs loading when you switch on
Use F-Secure as your anti-virus software as it also blocks spyware, malware and spam. You have to pay for this, but is much better than Norton or Mcafee and uses far less of your computers resources.
Run at least three anti-spyware programs each week because you will find that some will find spyware that the others can miss.
Backup the data on your PC on a regular basis. You can get a 250 Gb external hard drives for about £50, these days.
