Macintosh users have to be as careful with viruses as Windows users, there might be less viruses for Mac computers but they do exist, the Apple Flashback virus is a good example. As Mac OS X market share increases so will the number of virus writers targeting the Mac operating system.
With some in the Apple Mac community spreading the false rumour that they can’t be infected by malware, it makes it easier for malicious hackers to install a trojan. As long as someone can make money stealing banking credentials and private data off Mac computer users, the risk of computer viruses for Macs will remain.
