PesrPatrol cleans up system but cydoor keeps installing

Everytime I go to my PestPatrol goes wild and cleans up all the rubbish that is put on my pc (running Windows 2000 Professional).

But now, even though I no longer visit cydoor keeps installing itself. PestPatrol detects and deletes it but

a: Where is it coming from now.

b: Can some securiry guru load and tell me what is going on with this site?

Thanks in advance.

Let me take a guess....

You have some P2P software installed, kazza, imesh, bearshare, grokster, ect....

A lot of free P2P application will detect if you delete the spyware, and then will download and install new copies.

Do you have P2P software installed, or any other freeware programs?

Just finished examining the source to the page you specified and it's clean.... no activex controls, no dll's, no .cab files, and the .js files look harmless. I don't know why you are getting any popups or messages from this page....

Hello kjuliff =)

There must be some other thing which is going wrong on your system, so try this, get msconfig for Win2000 from here >>
Then use msconfig to untick unwanted progrmas as described here >>
Then Download these tools and install them:
AdAware ==>
SpyBot  ==>
CoolWebShredder ==>
Stinger ==>

Then Run all of them one by one in safemode and delete everything they detect.
Then delete the temporary internet files and history of IE
and run Disk Cleanup on ur hard drive to delete those temp and junk files.
Restart back in Normal Mode to check for the problems now ?? :)

If still the same, then Download HijackThis v1.98.2 from here, run it and Save the LOG file:

Then Post that log at this site >>
and it will automatically analyse it for u,,, Fix the entries which it labels as Nasty :)
To Fix, check the lines in Hijackthis scan and click on Fix Checked !!

HJT Log Tutoriol >>

CAUTION: Before fixing the entries in hijackthis, make sure that they are really Nasty and can be deleted, better u first research for it on Google and then when u will confirm that they shud be deleted, Fix them. And whenever u run Hijackthis, run it from a New folder on ur desktop, so that in case of any problem, u can take advantages of its created backups of fixed items. And in case if u still face problems in dealing with it, just analyse ur log at the above site, and then scroll down where u will see a Save Analyse button, hit it and it will save ur Log Analysation, then copy the link of that page and paste it here, and we will check it for u :)

Thanks for the responses so far especually SheharyaarSaahil 's. I will do those things as suggested tonight.

There is a new development. I can NOW access from my work. I am not getting blocked. I suspect something has changed on that site in the last few days!
sure, good luck and keep us informed :)
Go to and download the Giant AntiSpyware free trial. If you run that program, you should be able to find alot more crap than most of the other programs (has larger database).

Here are the basic registry keys created:

              Open regedit

              Navigate to and delete the keys (if they exist):

                           HKEY_USERS\.DEFAULT\Software\Cydoor Services
                           HKEY_CURRENT_USER\Software\Cydoor Services

Exit the Registry Editor.

I meant to split the points the other way around!  I wanted most points to go to SheharyaarSaahil

Don't know what happened. Can this be corrected?
