Been offline for a few days thanks to Norton 360 which killed my laptop. I luckily had made a backup of files a week ago (first time in years!). Unfortunately, Nero also played naughty and I only managed to restore some stuff.
After rebuilding my laptop, installing Norton 360 again, trying to restore backup, seeing death again, raging at the machine, rebuilding again, restoring with some success without Norton - I concluded that it was the work of the devil so I would get a refund.
The only good thing I can say about Symantec corp is that I got my refund very quickly last night at 1am. Makes me think they are dealing with Norton death so regularly that they have the refund machine working efficiently.
So now I'm on the hunt for a AV that won't kill my laptop!
