I have had good experiances with them (Norton) if some website auto downloads a virus it knows and deletes it after telling you it has kept my computers safe and I am used to the interface
Fair enough. I just find Norton such a system hog, though. On the default settings, it scans each and every file each time it's accessed, which cripples game performance and also causes Windows to behave quite slowly at times. Also, three minute bootups are unacceptable for me - and that is a best case scenario with Norton.
Then there is the scanner itself. It is slow. 100,000 files in Norton takes well over an hour. The same number of files with AVG takes 22 minutes. Less than a third of the time. And that is with 'scan within archives' 'scan
all files' and heuristics enabled.
I've heard that the Corporate Edition (without all the bull front end prettiness) is faster and less system intensive. But I've never managed to get hold of a copy, as the universities I've worked at have all bought the 'consumer' version...
