I had norton and renewed subs for past two years. upgraded system to xp few weeks ago. needless to say small problems, one of which was norton. told me that i would have to re-install it from disk. tried to re-install, told me that windows detected 'newer version' of windows and wouldn't allow reinstall. So caught in a loop - no norton on comuter - computer refusing to reinstall older disk version. Rang Norton for advice, easier to piss into a gale force wind. Now with AVG and Kerio firewall. Kerio firewell freebie expires tomorrow but I am going to let it expire and just use the free version as they have a bit on their site about being bought out by some other company and they intend to keep the free version for home users. since I installed Kerio, AVG has not detected a single virus. M Bond : Avg are only €40 incl vat for two years if you are worried.
