Every comparison I've seen between F-Secure and Norton puts F-Secure ahead.
It finds more and gets quicker updates. I've used it for 18 months with
zero problems or infections. I have just decided to try elsewhere though as
they want the same money each year for a licence as for the complete
package, surely there should be a reduced charge? I also didn't like the
fact that you can't manually download a virus signature file for the
combined AV/firewall, you have to rely on automatic updates.
