Linux-based computers are five times more likely to send spam than Windows
PCs, relative to market share, according to the latest MessageLabs Intelligence
Report from Symantec Hosted Services.
The firm obtained the passive fingerprinting signatures of spam email traffic
for the first time in this month's report, in order to learn the type of
operating system running on the infected spam-sending machines.
Paul Wood, senior analyst for Symantec Hosted Services, explained that the
common perception has often been that Windows machines are responsible for the
majority of spam given the high number of infections.
