We all assume that MAC does not need any additional antivirus, and their inbuilt security scanner is enough to protect our Mac books, but recently Apple admitted, that having another layer of Virus safety would be good.
The reason behind this is, as the technology is advancing Virus programmers are becoming intelligent and they are developing more sophisticated Virus/ Spywares/ Malwares. These “Build to Kill” programs actually are very smart, they reside in your PC and instead of doing anything which is directly harmful to you, these days they simply steal your personal information and uploads to programmer’s database.
