I'm sorda lost with what your saying..........I'm assuming that you had a lot of typos in you post.........
I actually disagree Kapersky definatly one of the best.. For shear usage and pliable protection it equals Zonealrm but with better antvirus.
The best thing about Zone Alarm is that there is a free edition for a firewall, but we're talking about AntiVirus products here........
ZA has a AV product but since it's not free I've never really went out of my way to try it........Kapersky has a firewall but that also not free so same as above for reasoning of not trying it......I have never seen rave reviews on either also........
I agree that most only need AGV or similar but if you comit to loads of Internet time and rarely reboot, then you need somthing that will keep your machine protected 247.
Your machine would be protected aslong as you update your virus program frequently......Having your computer on for an 1hr a day or having it on 365 days in a row isn't gonna change the chance that you get a virus.....Provided your running a decent AV prog with updated definitions.........
your computer habits time-wise are NOT gonna have much of an effect on which AV you should choose to have your comp protected by........ besides the fact that if your computer is off you can't DL/open attachments ......
The biggest factor obviously is knowing what your downloading/attachments u open........having a clue about how big the file should be or knowing your source would help also.......Most computer experts don't even need an AV, I'm not that gifted yet....lol...........
I've had three viruses in 6 years with my comp.......2 of them were within my first three months of using my computer, before running into DK, slyck, other forums..........1 was because I was being stupid and tryed to cut corners when I really didn't need to......
It really depends on whats your budget or what program interface suits you best
My opinion from personal trial and by reading other opinions would be
Free.....AVG
PAID......Nod-32
Cracked........ Nod 32
Right now I use McAfee because it came free with the internet service
