You've not provided any information regarding the problem.  In order for someone to help, they would need to know the model of computer, the OS, any error messages that you've seen, what you may have installed just prior to the problem, etc.  Without some more detailed information, not even Ms Cleo could help you.

It would probably help to know whether there's actually a working anti-virus program installed on the system, whether the definitions have been updated recently, and whether or not a system scan for viruses has been performed, too.

Thank you all so much, but I did find out what it was.

 

YUP...

Sure enough, the Blaster worm got in, but fixed it.

Again,

Really appreciate your help~
