Hidden boot file for KeyLogger2

[swat253]

I recently inherited a used HP Pavilion that had a keylogger program installed. It apparently loaded each time the PC was started and ran in a stealth mode. After about 3 weeks of use, I re-started my PC upon returning from vacation and got a default text box stating that the program had been started 25 times and I needed to register it. I tried everything I knew to locate the application and finally found the hidden folder. I tried to uninstall it but it is password protected. Any ideas as to how I can locate the hidden associated files or how I can keep it from starting everytime I reboot? The text box appears just prior to Windows start-up and the program does not show up in "ctrl+alt+del" window.

Application; Keylogger2
File name; KL2.exe

The program author wants $5 cash mailed to him, to a foreign country of course, to provide me with a shareware registration password. I don't want the software....I just want to get rid of it.
Thanks

Boot with a boot disk and format the drive......use a wipe utility and then reinstall everything. In the meantime change any passwords, private account data, etc. A stealth keylooger that you haven't installed....no telling how legitemate is is, but not something I would want hanging around.
