Personal computers that play unwitting host to "zombie" code are proliferating at a startling pace, according to a new report.
Incidents involving the malicious code, also known as "bot" code, reached 13,000 from April through June, according to a report from antivirus software maker McAfee. That's quadruple the number tracked by the company in the previous three months. McAfee estimated that 63 per cent more machines were exploited by bot programs and by spyware and adware - their slightly less insidious but more common cousins - in the first six months of this year than in the whole of last year. - Silicon.Com
