Since you haven't given us any details about your computer, your
operating system, or what makes you think you've got a keylogger, all I
can do is suggest you go through the following general malware removal
steps. Do everything methodically, with updated tools in Safe Mode.
Some keyloggers have a physical component which sits between your
computer and the keyboard connection, so make sure you examine your
machine's outside too.

First delete all Temporary and Temporary Internet Files. For IE's
Temporary Files, go to Control Panel>Internet Options>General tab.
You'll see where you can delete cookies and files. For Firefox, clear
its cache by going to Tools>Options>Privacy>Cache> Clear. For Windows
Temporary files, Start>Run cleanmgr [enter]. Then follow these detailed
malware removal steps, doing everything with updated tools in Safe
Mode. You can find all the links to referenced programs and sites on
my website here:

1) Scan in Safe Mode with current version (not earlier than 2004)
antivirus using updated definitions.

Before you remove malware, get LSPFix or WinSockFix for XP - see links
below.

2) Remove spyware with Spybot Search & Destroy and Ad-aware. These
programs are free, so use them both since they complement each other.
There is a new version of CWShredder from Intermute. I would not
install the other Intermute programs, however. Alternately, there are
CoolWebSearch malware removal steps at SilentRunners.

Be sure to update these programs before running, and it is a good idea
to do virus/spyware scans in Safe Mode. Make sure you are able to see
all hidden files and extensions (View tab in Folder Options).

If the malware remains even after you used Ad-aware and Spybot, you can
scan with HijackThis. HijackThis is an excellent tool to discover and
disable hijackers, but it requires expert skill. See the links on my
website for a HijackThis tutorial and places where you can post your
HJT log. Again, this is an expert tool and novices should get help
with it.

3) If you are running Windows ME or XP, you should disable/enable System
Restore after the system is clean because malware will be in the
Restore Points. With ME, you must disable System Restore completely.
With XP, you can delete all but the most recent (presumably clean)
System Restore point from the More Options section of Disk Cleanup
(Run>cleanmgr).

4) Make sure you've visited Windows Update and applied all security
patches. Do not install driver updates from Windows Update.

5) Run a firewall.
