I have really tried to pay attention to security not only for me but my 11 year old is on my routers network. I have him firmly clamped down using MS family safety but if there is a weak link it will be there. I also have team viewer installed but hidden on his computer and I can time to time check up on him (hehe)
After all the security suites that have come on scene its enough to make ones eyes glaze over. I have tried more than my share. I guess I also like playing with new toys and gadgets (yes I'm the kid that took grandmas can opener apart). The security software industry is keenly aware of peoples computing habits and take full advantage of it.
I have a single core amd64 processor and 2 gigs of ram, so what doesn't quite work for me will fly on a newer more powerful machine. One has to find what fits. After much experimenting, what works for me is a multi layer approach. Avira, Sunbelt firewall (behind a router) and I---t360 play well together and super antispyware for on demand scan. I can honestly say I tried other approaches and have settled with these.
I also believe one can provide themselves with excellent protection and still not give up performance. (and lets not forget common sense) Again protection has to be tailor made to ones machine.
