I had this crap on my PC. It took me a few days to get rid of it, but my PC never worked the same. Might as well wipe the hard drive and start over. Sorry. That stuff is BAAAD.

I have run into this program many times...and it can be a pain to remove. I use the "Three Amigos" to remove all spyware and adware.
Download:
Hijack This!, Spybot Search & Destroy, & Lavasoft Ad-aware SE (Spybot & Ad-Aware are both avilable through www.cnet.com)

Once you get them downloaded, install & update Spybot & Ad-Aware, but do not start a scan. HiJack This just gets extracted to a folder on your HD.

Reboot your computer to Safe Mode by hitting the F8 key after the BIOS screen.
In Safe Mode go to Add/Remove programs and try removing the spyware programs.
Still in Safe Mode, run Hijack This and remove any suspicious entries...Especially BHOs that you did not install. You may see entries for Spybot & Ad-Aware (leave those). Check the boxes next to what you want to remove and click "Fix Checked". (You can reboot at this point, but if you do, go back to Safe Mode)
Next, run Ad-Aware and remove any critical items it finds. When you run Spybot, under Mode, choose Advanced, then go to Settings. In there, right click on one of hte entries and choose "Deselect All". Then you can go to Immunize and immunize your system & set your IE block settings. Go to teh Spybot S&D section and click "Check for problems"

Ad-Aware & Spybot will take a while to run, but they both do a pretty good job. Spybot will find some things it can't fix and will prompt to run itself at next startup. Go ahead, it will run before the Explorer shell starts.
Go ahead and reboot normally. When Windows starts, Spybot will run (if you told it to). Sometimes it won't find anything on the second run because the registry entries it found in Safe Mode were removed by Hijack This! or Ad-Aware, the registry won't reflect the changes until the machine is rebooted.

Also check the Hosts file in \windir\system32\drivers\etc\ remove ahything that looks suspicious except the localhost entry

Good Luck!
