Anti-virus software? Terrible stuff. Slows down everything, always making the wrong decisions and annoying the hell out of me. Never touch it.
Spyware checkers? Sure. Free and easy.
Upgrades? Absolutely never. For every upgrade you download to plug a hole, another one is opened. This becomes a perpetual cycle. Not many viruses are written these days to attack 10-year old software, so I’m not worried, and besides, I have most of the dangerous features of programs turned off.
I’m on the Internet 8 hours a day and have yet to become infected. Sure, I get 50 viruses emailed to me daily. They’re fun to watch, I recognize most of them, I even collect them. I just don’t execute them.
Of course there’s always the first time…
I spend much of my time cleaning viruses off of other people’s computers. The ones that have Norton or MacAfee installed, that is. The virus slips by the defenses, disables Norton, starts eating away at the innards, and they call me. It’s job security.
