If your friend started with a good virusscanner and uptodate virusdefinitions than he wouldn't have that much viruses.

Another point; this is a press release from NEWS (a music distributor):
"A prestigious Belgian label such as Bonzai going bankrupt cannot and should not go unnoticed. Uncontrolled illegal copying and downloading of music is taking its toll; after a long series of dismissals and redundancies in several companies, Bonzai has now also lost the battle and has had to close down.

For years, Bonzai headed the Belgian dance scene with international successes and artists such as Push, Energy 52 and Yves Deruyter, to name but a few. In addition, it also provided a solid professional platform for emerging Belgian talent.

The record company News, also acting as a distributor for the Bonzai vinyl catalogue, thoroughly regrets that a long-lasting collaboration with a partner and a friend should end this way: "We hope that this makes everyone who's into illegally copying and downloading music, think about the fact that the music industry, and the dance industry in particular, is in serious trouble." News therefore hopes that there will soon be a statutory regulation concerning downloading and copying."
