After looking over a few sites, I fairly certain have the latest version of
VX2 (the Look2Me variant of CoolWebSearch, if I'm not mistaken).
Try CWShredder
(
http://www.trendmicro.com/ftp/products/online-tools/cwshredder.exe) to
remove it. This will remove even the Look2Me version of CoolWebSearch, which
is what's infecting your system.
If that fails, try doing what's listed on the following links,
http://pcpitstop.invisionzone.com/index.php?showtopic=102743 and
http://www.bullguard.com/forum/12/Searc-h-and-look2me-help_21616.html.
Go to c:\windows\prefetch (XP only) and delete the entire contents of the
folder, but not the folder itself. Not doing so can cause the infection to
reappear when you launch IE and other apps that the infection has become
linked to through the prefetch folder.
Hopefully this will solve the problem.
NOTE: Make certain to always have MSAS' Real-time Protection active as it's
the best real-time protection available out there for antispyware apps. DO
NOT run any other antispyware app's real-time protection (i.e., Spybot's
Immunization and ResidentIE, ewido's background guards, etc.) as well, as
they will conflict. This can cause infections to slip past the protection
net and onto your system. As always, it's never a good idea to run two or
more AV apps, nor two or more firewalls at the same time. The same is true
with real-time protection when it comes to antispyware apps.
My system was infected with an earlier variant of CoolWebSearch. After
removing it, I made certain that Real-time Protection was turned on in MSAS,
and I haven't gotten infected since. I removed the infection with the trial
version of Giant AntiSpyware just days before MS bought out Giant Company.
