Early versions of CoolwebSearch were trivial to defeat (ie adaware). The later versions are becoming increasingly annoying. The latest versions of CoolWeb laugh at most of the spy-ware removal tools. Use About Buster (google) and HiJackThis. About Buster will do most of your heavy lifting, then use HJT to scrap the rest of the leftover debris. The usual "safe mode" and "restore point" steps apply.

I use "HijackThis" and have had success beating it.  For most of my
intensive Adware removal, I copy HiJackThis and CWShredder to the hard disk
and then reboot the machine in safe mode.  Then I manually kill all of the
processes that it will allow me to kill...  then run Hijackthis and
cwshredder and take note of where the files are.  I then go in and manually
delete those files.   CoolWebSearch hasn't been nearly as much problem for
us as "TVMedia" and "WinTools" or a few of the other ones that have multiple
threads and/or system services that watch the system processes and restart
each other when one of them is killed.  WinTools is an amazingly resilient
program that uses this method with 2 processes PLUS a system service all
watching each other.

Interestingly enough, aren't they one of the companies who sued Symantec
when they tried to add CWS as a "virus" to their definitions. After all,
it's an "advertising engine" not a "virus" and they (like GMT and Gator)
have been aggressive in pressing legal action against anyone who tries to
"automatically" remove their "program".

Interesting bug going around, coolwebsearch, has anyone been successful in
removing this virus from a system? It looks like it recreates the DLL under
c:\windows\system32 and renames it after a few reboots. It's pretty annoying
and I haven't been able to fully contain it.

Thoughts? Suggestions? I've used highjackthis, cwshredder and a few spyware
detectors, but nothing is really fixing the problem.

Thanks,

-Wes
