[wayne_uk]

What the hell is this all about ? , kinda freaked me out,first time its happened,pop-up came up,told me to save things and then proceeded to shut down and restart all by itself,did a virusscan and i had something called "hauntpc.exe" somewhere !! (which i deleted pronto ) are these 2 things related ??

thanks for any info..

btw its just me on my pc,not linked to anything.
