I may have mentioned this before but my mate Roy is a sucker for this type of rubbish.
He's always looking for something for free to 'sort his computer out'.
What he's only now coming to realise is that if he didn't install so much crap his computer wouldn't need sorting out. I've lost count of the amoount of reinstalls I've done for him.
When I built his i7 machine I told him he's on his own, he messes up he has to sort it himself.
So far, so good.
And I only weaned him off Nortons just over a year ago....
So, let this be a warning, unless freebie (or paid for, for that matter) software is recommended by one or more long standing forum members here - beware.
