whenever questions like these are asked people always just recommend getting Firefox (which isn't a bad idea) - BUT nine times out of ten the source of the "popups" is actually the result of spyware/adware on the computer
The question probably would not be asked otherwise
I suggest you do basic malware scanning/cleaning...
You do want to disable your Windows System Restore before cleaning, otherwise the virus can resurface thru the restore files. http://support.microsoft.com/kb/310405
if you do a search for the name of the malware there will sometimes be a tool available to clean the specific malware. you also should do general cleaning.
all of these are free:
Run CCleaner first (just run it with the default settings). You'll get a better idea what infections you have when running anti-spyware scans. http://www.filehippo.com/download_cclean…
Spybot: http://www.spybot.info/en/index.html
set it up as shown here: http://www.phpbbserver.com/stevie19605/v…
Also scan with Ad-Aware: http://www.lavasoftusa.com/products/ad_a…
AVG Anit-spyware: http://free.grisoft.com/freeweb.php/doc/…
I've heard others recommend this app instead of Spybot and Ad-aware, you might want to give it a try first: http://www.superantispyware.com/
Also, Javacool Software's SpywareBlaster for resident protection: http://www.javacoolsoftware.com/spywareb…
You can get BitDefender as an on-demand virus scanner:

You don't want to run two resident anti-virus programs but using one as an on-demand scanner is fine.
