Here are some tips and tricks that i just learned.

Remember that shutdown message that popped up when an attempt to infect you w/ msblaster.exe was executed?

What that popup is, is a timmed shutdown application that is located in c:\windows\system23\shutdown.exe

You can execute that exact popup with a command like this
Start Menu>>Run>> shutdown -s -t 300

Here is what that command means
-s states that you want to shutdown, -r can also be used to restart the machine.

-t sets a time to shutdown, -t <number of seconds>

This command can also be executed on your machine from another machine, so if it happend you will know atleat a little about it.

With msblaster.exe you would have to download a patch and only people who could download that 5.5 mb patch in 30 seconds were able to. With me, everytime that download would get started i would get that popup and my computer would shutdown.

Here is how you can avoid having you computer shutdown eithor by a virus (msblaster) or any other invader. When the shutdown application is executed you are able to view it. Once you know it is running just simply goto Start Menu>>Run>> shutdown -a

-a stands for Abort

the -a command will close the current shutdown process. This is very helpfull when downloading a patch for a virus that uses the shutdown command.
