Sooner or later markets reach equilibrium. Computer virus markets, like others, are not different indeed. Some users of Mac environments thought they were safe from viruses but it is now part of a myth. The past 16th November was discovered the 1st worm for Apple’s OSX. It is not much aggressive; it is just a proof of concept that malware is not only possible but a real menace on this platform.
Apple’s strategy of migrating their platform from Power PC to Intel could be a signal that OS X could become a much more popular OS in the future. If Apple’s countermeasures against copy and deployment of OS X on standard PC ( Today it’s possible but illegal) fails, the population of OSX-suited (or hybrid) malware will increase soon. Malware it’s not about technology it’s a market phenomenon.
