1. Simply rename the file and see if you get an error message.
2. Find out where it's started from (somewhere in the registry, I assume) and remove that.
It's some trial and error, I'm afraid. Don't do anything you can't turn back.
I recently removed a Lexmark printer from my computer, but I do not know how to remove the lexpps.exe file which is still on the computer, and still requesting internet access. The computer runs Windows XP.
I'd appreciate any help you can give me!
