Anti-Virus? Anti-Spyware? Both?

I hate anti-virus software. It slows down a person's computer SOOOOOOO much, so needless to say, I don't have any on my computer.

As far as anti-spyware, I don't have that either since I've never had a need for it as I don't install retarded programs. (Didn't know any better when I was 16 or so and installed Kazaa.)

I use FireFox with a NoScript add-on and don't visit any shady sites. I figure that it keeps me safe enough. Although I do have my Windows Firewall shut off (so annoying trying to run P2P software with it on) and a single port forwarded to my computer through my router for Bittorrent.

Hehehe, it's funny how paranoid people get. Even though my last roommate is about as knowledgeable as I am about computers, he raised hell because I forwarded a port to MY local IP address through our router for bittorrent, saying I was putting "us" at risk. While it is true that I am putting myself at risk to a small degree, I've never had my computer affected in a negative way because of a single forwarded port, let alone another computer on the local network that doesn't have any ports forwarded to it.

Also, my computer illiterate aunt, who uses her computer for little more than e-mail and casual web browsing thinks I'm nuts that I don't use virus protection. She bought and installed Norton and needless to say her six-month old computer now runs like a used two-year old computer. >_>

Jam it back in, in the dark.
