Thats a fair few.
Try getting some free software, not trialware such as this:

Spybot Search and desktroy (S&D), wideley used. Free and seems to do
the job. Also have you cleaned out your internet cache? If you are
using internet explorer go in to, on the context menu- tools>Internet
Options then click delete cookie, delete files (also check delete
offline content) and if you realy want to you can clear your browsing
history while your at it. Alough not nessicary.
This will remove any cookie based adware, normally just harmless
tracking from websites to see if your are a frequent visitor ect often
found on pornographic webistes.
Spybot s&d will do the rest of it for you.
like i say check out
http://www.spybot.info/en/download/index.html
Thats probly the best scanner out at the moment. Free that is.
Good luck.
Need any more help just ask.

P.S try to elaborate a bit more on your question if you want more
specific answers. Eg when do you get the popups, and set intervals waht
website dose it link to. are they all from the same namespace. Do you
get popups when not browsing the net Or disconnected from theinternet.
what browser you are using.
Take care.
