Apple is a company that comes with a range of computers. In fact these computers were the ones that were the very first in the market to come up with the idea of graphical interface. In the old versions of other computers you need to type command line to get results. Though the Macintosh is the best in the market it is still being threatened by malware and antivirus. Therefore if you are about to buy a Macintosh or have already bought one then you should be well educated in terms of virus protection.
ClamXav
ClamXav is a free application that eliminates viruses from your Macintosh. The good news is that it is free of cost and can be downloaded instantly through high internet speed. It scans your computer for various malwares and viruses and later eliminates them on demand.
Since it is free of cost it does has some limitations. For example it is only an on demand scanner. Which means you will have to scan for the viruses in a particular folder or drive. Unless you do so the protection is invalid. Moreover, it is does not eliminates high and advanced Trojans and malwares so you should be careful while using this application.
IN short though the application is free it is not worth it because in the long run your computer will be infected with virus.
Mac Norton 11
This application has all the features of an advanced antivirus program. It has the ability to scan your computer on demand or scan it in real time while you are still working in yuour Macintosh. In short this application is useful if you are looking for or working over the Macintosh the whole time. But again there is some disadvantages in it. the application though has all the features of an advanced antivirus program it still lacks some of the ability to eliminate complex viruses. For example, if the virus is sourced from a Macintosh then it would be hard to detect the threat by this Norton 11 for Mac.
Note: This application is given by Symantec
MacAfee for Mac
This is most upgraded antivirus for better protection of your computer/Macintosh. It has better usability and all the necessary features. In fact it is also the one which detects most of the threats. However, the problem comes in that it is meant for commercial use. You will have to purchase three licenses of the software. If you are an individual then this is not meant for you.
