Now I have a Mac, I don't need any of this sort of thing on my laptop, BUT dd has my old PC and Norton antivirus is about to run out. In addition to it taking up loads of space and memeory, it costs a lot? Was thinking of uninstalling it, and going for a free antivirus programme. Is AVG any good? Dd doesn't send/ receive emails, just browses, mainly cbeebies and Barbie websites
