I downloaded Norton ant virus and firewall yet someone keeps coming on to my computer and turning it off. I've downloaded other Norton products to replace the above and the same keeps happening.
Also i have been downloading a film and someone and suddenly my computer crashes and I lose all my film.
Is there any reliable software that has been tested? Also can I block people from attacking me, perhaps block my details or whatever?
I would be very appreciative of any help to protect my system and to know if there is a means of knowing good downloads from people who seem to use it as a means to screw up your computer??
