CLEANING UP THE PC

hmmm...today when i switched on my pc, a virus had bumped up on my screen and says that it will shut down the window in 60 seconds... i was shocked.. i quickly call my IT expert fren and ask for help... (FOC) He taught me how to destroy that virus by running a programme.. So I ask him to send the programme to me (I'm using my bro pc to receive the file and save it into a diskette). Then...i'm fighting with the virus, hoping that i can managed to run the programme b4 the virus shut me down... never been so stress out...hahahaha...finally my bro come to save me..he help me to delay the virus to pop up (dunno how he does it) then we managed to run the programme and stop the virus...after the whole thing is done it's already 1.30 am (the virus detected around 12am) So sleepy now...-O-..............nite nite :)
