Sounds like you've probably been infested with spyware. If you use IE, and especially if you haven't installed SP2 yet, this is almost a given.
Start by downloading a few anti-spyware programs, let each of them scan your system, and then stop using IE. Use something safer, like Mozilla Firefox.
Even if those don't solve your problem, it's a good idea to do anyway, and you can always come back and say it didn't work.
everytime I log in to my computer, a pop-up message appears,cannot find "dust.exe". How can I get rid of it. Pls help.
