I am an advocate of anti-virus software. Before writing on technology, I was editor for an academic publication in Washington, DC. It was policy professors make submissions on diskette—which invariably were infected with computer bugs. And on a network this was a disaster. Idiot editors would copy files from unchecked disks to their PCs and infect every computer.
You might think you are safe from this kind of contamination, but, believe me, you are not. Of potentially disastrous consequences to small businesses is a new type of macro virus that targets word processing or spreadsheet documents, mainly Microsoft Word and Excel. Since most people use these programs, this is a big problem.
