This may sound dramatic, I'm both famous and infamous for making surgical cuts, and there's definitely no offense here but: if you attend dangerous sites like p*rn or t*rrent ones without appropriate security, or you neglect the warnings, your computer is bound to stall, partially or totally.
Even such a legitimate site as Youtube has it problems: expressing open views of mind there, concerning U2 music which I love, I got my computer hacked down twice in a fortnight.
Dunno? But since it is a matter worth of a thought, I took the courage to write this. If you go out in stormy weather, it's recommended you put your rubber boots on?
Just a minor brainstorm...
