Ugh, that could be a problem. Well, let's try all the basics first:

Try a online antivirus scanner and a online anti-adware/malware/spyware scanner in safe mode with network to clean up your computer.

Disable "System Restore" for Windows Me and XP, then restart your PC to clean your system restore points for viruses, spyware, adware etc.

Now restart in safe mode.
To get in safe mode, Press "F8" upon boot up.
Select "Safe mode with Networking".
Go to Start – Run - type iexplore BitDefender Online Scanner - Free Online Virus Scan Enter(ok).
Do a full system scan. If something is found, delete it, reboot and do the same again in safe mode with network.
When that scan does not find anything you reboot again in safe mode with network.
Go to Start – Run – type iexplore ewido is AVG - anti-spyware, anti-malware and anti-virus software Enter(ok).
Do a full system scan. If something is found, delete it, reboot and do the same again in safe mode with network.

**NOTE: Do NOT do anything else with your computer when scanning. This because you can start virus/adware/spyware/malware manually.

When no one of these scanners are showing anything you can reboot back to normal mode.
Turn on "System Restore".
--------------------
You need to get one antivirus program, one firewall, pop up blocker and some spyware/adware/malware removers if you don't have it.
I use Norton Internet Security (antivirus, spyware, firewall, add blocker, mail spamfilter, pop up blocker etc) Ad Aware, Spybot and more on my desktop running XP Home SP2 with Firefox and Yahoo Toolbar with pop up blocker and Windows pop up blocker on.
On my laptop I use antivirus and firewall. Firefox is my standard.
I have no virus, spyware, adware, pop ups etc on my computers.
Mozilla Firefox and Opera are safer browsers to use then Internet Explorer.
Firefox web browser | Faster, more secure, & customizable
Opera browser: Home page

SUPERAntiSpyware Free.
SUPERAntiSpyware.com - AntiAdware, AntiSpyware, AntiMalware!

Spybot - Search & Destroy detects and removes spyware, a relatively new kind of threat not yet covered by common anti-virus applications. Spyware silently tracks your surfing behaviour to create a marketing profile for you that is transmitted without your knowledge to the compilers and sold to advertising companies. If you see new toolbars in your Internet Explorer that you haven't intentionally installed, if your browser crashes inexplicably, or if your home page has been "hijacked" (or changed without your knowledge), your computer is most probably infected with spyware. Even if you don't see the symptoms, your computer may be infected, because more and more spyware is emerging. Spybot-S&D is free, so there's no harm giving it a try to see if something has invaded your computer.

AVG Anti-Rootkit Free.
AVG Anti-Rootkit is a powerful tool with state-of-the-art technology for detection and removal of rootkits. Rootkits are used to hide the presence of a malicious object like Trojans or keyloggers on your computer. If a threat uses rootkit technology to hide itself it is very hard to find the malware on your PC. AVG Anti-Rootkit gives you the power to find and delete the rootkit and to uncover the threat the rootkit is hiding.

CCleaner is a freeware system optimization and privacy tool. It removes unused files from your system - allowing Windows to run faster and freeing up valuable hard disk space. It also cleans traces of your online activities such as your Internet history. But the best part is that it's fast and contains NO spyware or adware.
