Ive just had my pc crash ,and the man at repair centre said my norton internet security prog has gone as he had to reinstall windows ,but hes put in a free avg prog saying that will be o/k, and Ive been told I cant reinstall norton anyway ,another 40 quid down the drain ,my question is do I have to have any other free security progs to run along with avg ,I am with bt so I get a free spy prog ,it comes with option 1 ,thank you in advance
