No it was not wet. It was running fine. For couple of days it was left alone with no Anti-Virus because I had restored the system and had not had chance to install and thats when suddenly the screen appeared foggy.

It could well be malfunctioning screen but my suspicion to being virus is because at the beginning the fog was in the middle part of the screen and was not dense, within couple of hours the fog started getting dense and started spreading across the screen and to the edges.

At the initial phase I tried to boot it up in SafeMode hoping I could restore to earlier state and may be try to install anti-virus but I was not able to move the cursor (i.e up and down arrow key) to chose SafeMode option. Not being able to use cursor to move up and down with arrow keys on safe mode also added the suspicion that it might be virus.

thanks.
