Or you can get a Mac and never have to deal with it. I have both in my home (I'm gradually shifting to all Mac) and the amount of time and aggravation involved in maintaining my Windows machines is enormous. Virtually zero with my Mac.
I was going to post the same thing about Mac. Apple's fraction of sales is so small that the platform is ignored by the creeps that write viruses, malware, spyware, etc. Just the same, I run a Linksys router with NAT, NetBarrier X3 that doesn't allow my machine to be a server or call out and Norton Antivirus. So far, no problems.
Now if only Apple would solve the bit-rot problem in Safari.
