Let’s look at some signs that may indicate that your Mac might be infected with a virus.

1) Listings and unexpected pop-up

Adware is becoming a growing problem on the Mac platform. If you’re seeing ads in places where they did not show up before, there’s a good chance you’ve installed something you should not have.

That security has My Mac?

The Mac has some defenses installed with OSX that must be kept safe from some of the malicious programs, however, as all measures are not completely foolproof. These are some of the OSX security tools:

Gatekeeper helps protect your Mac, preventing uninformed users from installing potentially dangerous software. By default, this means that you can not install anything outside the Mac App Store, but you can also configure it to block applications from unknown developers. Of course, many Mac users disable Gatekeeper completely so that they can run whatever software they want, including things that they have compiled themselves. The hope is that users know how well-informed to carefully evaluate the applications they download before installing.

Sandboxing: applications installed through the Mac App Store have limited access to the system, a limitation designed to stop an application before it can affect the entire operating system.

XProtect: officially calledQuarantine File, is the anti-malware program that I did not know I had! It is the art of OS X since 2009, and it is not like Windows antivirus, but it is completely invisible to most users. You can not open the program and run an analysis on your own, and you can not install updates manually. But if you have been infected by a known virus, it is very likely that the program will warn you. XProtect will stop you even before opening the infected files. The only problem may be Apple’s updates, sometimes too slow to react to new threats.

The low diffusion is another advantage often claimed in the past, but the Mac now has an increasing market share, but for a long time, there have been so few active computers with OS X, that the malware creators have not been bothered to make his destiny. Of course today, with a growing base of Mac users, it is worth less than before, but Windows remains the main target of malicious software manufacturers.
