Malicious Software on Mac Computers
While hackers and virus-makers have traditionally targeted Windows machines, there has been a slowly increasing threat over the past decade on Mac OS X.
This has been changing due to the increase of Mac users and Mac computers since the start of 2000. With the rising popularity of Mac OS X, and indeed the entire Apple brand, it might be time to protect yourself.
The best way to keep yourself protected, as with PC users, is to be smart yourself. If you avoid dodgy download websites, illegal software, and unsolicited emails, you are much less likely to get a virus. That is not to say that you can be completely safe however, and so installing antivirus software is a good protective step.
As Mac viruses and trojans are in their infancy, so is the antivirus software. Therefore, you will not see antivirus software that promises to destroy thousands of viruses because, simply, there aren't any.
Sophos Anti-Virus for Mac, PC Tools iAntivirus and AVG LinkScanner for Mac are three antivirus software tools that stand out from the rest. The Sophos and PC Tools iAntivirus packages act similarly to PC antivirus software, while AVG LinkScanner is a preventative tool.
