for moreesearch from security company Sophos finds one in every five Mac computers carries malware.
After analyzing 100,000 Macs running the firm's free anti-virus software program, Sophos discovered several Apple computers carrying Windows malware.
Also, about 1 in 36 Macs were carrying malware specifically targeting the Mac OS X operating system.
"Some Mac users may be relieved that they are seven times more likely to have Windows viruses, spyware and Trojans on their Macs than Mac OS X-specific malware, but Mac malware is surprisingly commonly encountered," said Graham Cluley, senior technology consultant at Sophos, in a statement.
