Why I don’t Use Anti-Virus
In order to explain fully why I do not use any kind of anti-virus on my personal computer. I must explain a bit about the way things used to be and the way they are now. This story is roughly chopped into three pieces ‘The way things where.’, ‘The way things are.’ and ‘OK so anti-virus is almost useless what do I do?’
‘The way things were’
Most of us are our family technicians, we are the people that setup Mom’s surround sound. When spyware/adware started to get bad we would get the call to come and take care of a friends computer. Often the computer would be spontaneously popping up ads and slowly chugging along hogging what little bandwidth the dial-up had. Along comes the tech friend with a few minor tools like hijackThis and a boot disk and hunts down the offending executable.
The old method for malware writers was a game of hide and seek. Without getting into too much technical detail there are a large handful of places to hide something to make it run at boot on a windows system. Hiding a request to make some code start up and obfuscating the where and the how is all malicious software could manage. In this day anti-virus software was very handy most of the time because it was trivial to remove most problematic programs when they where found. The scanning software did not need to be too fanatical about things since most badware really wasn’t that bad.
In the old days of bad software the payload was often something trivial, funny, or annoying but rarely if ever truly malicious. The Whale Virus filled your hard drive up by replicating itself zillions of times. The Yankee Doodle Virus made your internal speaker play the song for which it was named relentlessly. Most virus writers where not bad people and the few that where bad people knew that when a virus obliterates the system it is on it no longer has that system under its control and can no longer replicate itself.
At this time I recommended and sometimes even used anti-virus software.
And then things changed…


networks? What I call the ‘eggshell effect’, the hardening of the outside of the network has softened the inside.
