Access Blocked Virus warning

I currently can only access websites from help and support centre
if a try manually entering any url i see a poorly miss-spelt page
obviously trying to look like a microsoft warning of some kind.
It will only let me use one search engine which changes in
appearence each time but is the same site i believe.
All websites it allowes me to view have hsdoclc.dll in the title
which appears to be a file on my hard drive in windows/system32
if i remove it the next time explorer is run it replaces itself.
The search site it allows me to use is Fast-seek or something and
it only has ads for porn pharmocuticals and other useless rubbish.
I have never registered with any site such as this and this attack is
obviuosly intentional by them. I have tried removing and installing
internet explorer, disabling all ie add ons and no strange processes
are running.
This happened wthout my knowledge and not at the same time as
any software upddate or install so i dont understand how?
Can anyone help cos im aout of ideas and this is the
only site i can get to.

i have xp pro service pack 2 and all updates

Sounds Like a "Cool Web Search" variant. Have you tried running
"CWShredder"? You can dl it from another PC from Google. Also, run MSCONFIG
(Start>Run>msconfig). Disable any Services or Startup programs that seem out
of the ordinary.

It was a cws variant and cws shredder did work in the end thanx for
the help. I had never evn heard of cws before but it was the first
internet related problem i have had in about a year. It was really helpful
to know which program to look for. It worked fine but i have found i also
have to disable an add on in internet explorer to regain control of it even
after cws shredder is run it is called sasscln object it says (not verified)
after its name. Dont know if that is helpful to anyone else. But thanx again
for the help.
