Thanks Jo*mar
Is WOT a program I can download onto my laptop - does it review sites before they're downloaded?
Thanks for the other sites - I had read some of the Bleeping Computer forum & info. I'll look at the various options later today and figure out which of them might be manageable for me to attempt.

It's times like these I get really frustrated with computer manufacturers. They've well & truly forgotten the K.I.S.S principle when it comes to making computers for non-technical customers.
