A friend of mind ask me to come check her computer cause it wouldn't restart or shutdown.

When I got there I realized that MSBlast was on her computer and hence I removed it. However, removing MSBlast didn't solve the problem.

The problem is that the computer wouldn't restart using the start->Turn off computer->Restart option and it wouldn't shutdown either using that option. It will however shut down using ctrl-alt-del and then signing off the user and then shutdown at the signoff screen.

I am just wondering if any of you guys have experienced this problem before. Is it related to a virus or was that caused by MSBlast? Or does it have to do with something else?

Let me know what you guys think. Thanks.
