Tsk tsk... too many people, too many experts, too many opinions...

It's like someone asking if he needs an alarm system on the Ferrari he just bought... "dude, you need the l33t-t3ch 5000 version 34"... "no no old chap, you should go with the tatcher-4500 version 2.0"...

If you buy a Ferrari and you don't know **** about it, get a nice alarm system. If you buy a Ferrari and you do know everything about it, get an alarm system.
If you buy an alarm system, you'll get a KIA for free. Sell the KIA, and buy an ever nicer alarm system for your Ferrari. Drive over to Canada and show off your Ferrari to chsh and HT. Make them design an ever nicer alarm system for your Ferrari in exchange for a pissing contest in the trunk of your Ferrari. Clean out your trunk, have the winner install the alarm system, drive the Ferrari back to the US, park the Ferrari on the sidewalk because you're out of gas, have Gore come over to pee in the gastank, have Gore invite you all to pee in the gastank, and then take a nice nap. Or something.

Never knew it was that hard to answer a simple question...

Someone has one puter, has AV installed, and is worried about a firewall taking away system resources.

In stead of just answering the question, people get into a discussion about how KIA influences American car dealerships (OK, I made that part up...)

How hard is it to just say that a firewall does take away some of your system's resources, that AV-software is different from a firewall, that KIA is a car and not a bicycle?
