If you have XP with SP2 it has a popup blocker.
If you don't, download the Google Toolbar which has a very effective one.http://toolbar.google.com/googlebar.html
It sounds like you have been infected with adware/trojans/malware and need to remove them as well.
You need to be using Adaware SE (the most current verion) with the latest definitions files installed.http://www.lavasoftusa.com/software/adaware/
Download, then update definitions file before using. Run it at least twice initially and then at least weekly, updating definitions before each use.
You also need Spybot Search and Destroy,http://www.safer-networking.org/en/download/index.html
Be sure to update definitions before each scan.
The Microsoft Anti-Spyware Betahttp://www.microsoft.com/athome/security/s...re/default.mspx
(set to run daily at a time when your computer will be on)
and at least another program or two.
CW Shredder will also help eliminate trojans.http://www.majorgeeks.com/download4086.html
After you download AND UPDATE the above programs, shut down your system and reboot in safe mode.
If you are using Win ME or Win XP shut system restore OFF.
Do a scan with the web based anti-virus scan offered by Trend Micro.http://housecall.trendmicro.com/
Then run the above anti-spyware/malware programs while in safe mode, rebooting after completing each program's scan and deleting what they find, then running the next. It may take several scans by each application to accomplish the removal of all malware. One each is not sufficient.
Get the Yahoo tool bar (download from Yahoo.com) and run their anti-spyware program as well. (Works only with IE. WILL NOT WORK WITH FIREFOX).
All the applications I listed are freeware, which is all you need although there are paid versions of several of them.
I also recommend that you download the free version of Zone Alarm or some other good firewall and use it. The firewall that comes with Win XP is insufficient as it only blocks incoming traffic, not outgoing and will therefore allow a trojan to operate.
