Linux vs. Windows Viruses: Jack Clarke, European product manager at McAfee, said, "So we will be seeing more Linux viruses as the OS becomes more common and popular."
Mr. Clarke is wrong. [...]
According to Dr. Nic Peeling and Dr Julian Satchell's Analysis of the Impact of Open Source Software [...]:
"There are about 60,000 viruses known for Windows, 40 or so for the Macintosh, about 5 for commercial Unix versions, and perhaps 40 for Linux. Most of the Windows viruses are not important, but many hundreds have caused widespread damage. Two or three of the Macintosh viruses were widespread enough to be of importance. None of the Unix or Linux viruses became widespread - most were confined to the laboratory."
