Is your mac acting weird? and you are seeing ads that you can not explain, or your system is too slow, the problem may be the lack of malware.
In recent years, Macs have grown in popularity and expansion, and since then, and not coincidentally, also viruses for Mac. It is not, of course, the case of panic: Mac widespread infections are much less rare than the PC, but Here is a brief summary of the most common viruses in recent months.
The latest virus for Mac
Wirelurker was distributed through pirated software for Mac. He tried to infect an iPhone or iPad connected to the infected Mac, spread from platform to platform and collect the unique identifiers of the devices in the process. No Sida what is the objective of this malware.
I work infects users who downloaded the pirated software from the popular site The Pirate Bay. Infected Macs become part of a global botnet.
CoinThief infects users by masquerading as legitimate software and steals all bitcoins stored on the infected Mac. Dangerous
Flashback became famous in 2012 for the explosion, but it is one of the most dangerous.

All these infections have one thing in common: Mac is infected through software installed outside the Mac App Store. In some cases, the fault is pirated software, in others, it is third-party software.
So if you do not install the software from the Mac App Store, the risks decrease. Sure, there are some exploits of the system or browser and Java is a constant concern, so you need to stay up to date OSX because Apple regularly presents patch to correct problems.
If you install the software from the Mac App Store, you must be careful that the software before installing it (we use Google for a review, and the search for an official page).
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. This is even truer if you see pop-up ads, even when you are surfing the Internet. If you want to know more, read our sull’Adwareguide, how to identify it and how to eliminate it.
2) Is your Mac slowing down?
- Some Mac viruses become part of a Mac botnet , which is a global network of computers used for all kinds of things, often illegal. If your Mac is infected, it could be used without your knowledge to make a DDoS attack on a website, be part of a bitcoin mining network, or other actions that use the computing power of your Mac’s CPU!
- If the Mac is still slow, even if you do not have many programs open, this is a clear possibility.
- But in most cases, it is more , problems due to unnecessary files, too many installed programs or hard drive malfunction. You can use a program like this to speed up and clean your Mac.
3. A virus scan confirms the infection?
- Do you think your Mac may be infected? To know for sure, it is necessary to install an antivirus to scan your Mac and discover any type of infection, such as MacKeeper
- Virustotal Scan for Mac is a free online tool launched by Google for a few months.
AdwareMedic scans and removes an adware buonnumero on your Mac.
- This is a quick scan, so try it if you’re watching too much advertising.
If none of these instruments is anything, it is very unlikely that your Mac is infected.
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.
