Computer assistance, please

Theres something you can type into the start > run thingo...something like shutdown -a or something like that, which makes it so that your computer will not shut down remotley.

Basically nullifys the virus so you can get your fix downloaded and stuff. cant remember the exact command though.
 
If you're talking about software, it's program, or I'll put you in your grave. "Programme", although wrong, I'll let slide if you're talking about shows for entertainment.
