I faced this virus recently and beat it. Here's how:
There is a red shield in your taskbar with an X through it that says Your Computer is infected ! Then a popup box comes up that says Windows has detected spyware infection . click here to resolve this problem . When you click on the balloon, it says Question do you want to install registry cleaner ? And then it has two Yes and No buttons . When you click Yes on it, it downloads registry cleaner 3.1 which prompty does some scanning and then asks you to pay for it services. This is a huge scam. I think this "virus" was invented by their company to make some quick profits.
I tried using lavasoft's adaware with the latest updates (Feb 2007) and that didn't work. I tired using Spybot Search and Destroy with the latest updates and that didn't work. I even ran both of these with the administrator account in safemode and still nothing.
Finally I figured out that when I went into the task manager and stop the service ctpmon.exe it duplicates itself and then you'll have several red shields with X's through them. I did a google search on ctpmon.exe and you need to reboot in safemode, then go to
C:\windows\system32\ctpmon.exe
And delete the file. Then, you can go to http://www.ccleaner.com/ and download the latest version of ccleaner. I believe this is freeware. Install the program and run it. Click on the tabs until you see a box for startup programs. Located the startup for ctpmon and delete it. That's it! I also noticed several startup items for programs I deleted years back, so I cleaned those up as well. I noticed how quickly my computer started up after deleting those references that no longer existed.
