I don't care how long you've been building Windows based PC's, and I'm sorry but firewalls do NOT keep you from getting spyware, malware, adware, viruses, etc. Unless your firewall blocks port 80, or 110 (internet port and default email port). Most of the above go through those ports. Most spyware/adware comes through visiting various websites, not all of them porno websites either.
A lot of consumers aren't computer literate enough to know where to go and not where to go, even if they're told 80 times. This is the issue people have. Using a Mac, this isn't an issue at all. This is a major selling point. It doesn't matter why this isn't an issue on the Mac, the fact of the matter is, its not an issue.
Most virus scanners will slow your computer down. Its rare to get a virus scanner that JUST does virus scanning these days. Most will do worm protection, intrusion protection, spyware protection, etc. These are all little programs/engines that need to run upon startup, increasing startup times and eating up system resources, thus slowing down your computer. If you take your anti-virus off you'd probably be surprised how much faster your computer is. That is, unless you have some quad-core CPU with 8GB of RAM. Yes, they all do scanning in the background on the fly, but its the system resources and sometimes CPU cycles that it steals in the background that makes your computer slow.
Part of the problem is, we've scared people to death with viruses, spyware, malware, etc. So a lot think they need some top notch software package, sometimes 2 packages when sometimes all they need is something simple (i.e. Norton Antivirus instead of Norton Internet Security).
