Tarmac virus gets downloaded to a macOS system once OSX/Shlayer.D malware connects to a C&C server. Afterward, the malicious installation process begins and executes the trojan through this directory: Player.app/Contents/Resources/Player.app/Contents/MacOS/CB61E0A8408E by using administrative rights.
Continuously, Tarmac virus tries to get the victim to type in the administrator's password and if that is done, a fake Adobe Flash Player installer is displayed via WebView. Keep in mind that the trojan virus would be able to access the macOS nevermind if the password has been entered by the user himself or not.

Distribution tactics of trojan viruses
Trojan infections can be easily distributed through potentially unwanted programs such as adware. These odd apps might provide you with fake Adobe Flash Player installers that are known to include malware very often. Criminals like to camouflage their malware behind different app upgrades to give it a look of legitimacy.
You should keep all of your software regularly updated and always check on official reports about recently released updates. Continuously, include a strong antimalware program on your computer so that you will be informed if some type of camouflaged malware tries to sneak into your system unnoticed.
However, there are more ways of how trojan viruses might end up on your computer. These cyberthreats can be delivered through email spam that pretends to come from a reliable banking or healthcare-related organization. The malicious payload often comes inserted in an executable or word file that is attached to the bogus email message.
Last but not least, you should be aware of p2p sources such as The Pirate Bay or eMule as here you can get various cracked software and movies for free. Some criminals are likely to misuse these websites as they lack the required security.

How to prevent from getting mac viruses
Choose a proper web browser and improve your safety with a VPN tool
Online spying has got momentum in recent years and people are getting more and more interested in how to protect their privacy online. One of the basic means to add a layer of security – choose the most private and secure web browser. Although web browsers can't grant full privacy protection and security, some of them are much better at sandboxing, HTTPS upgrading, active content blocking, tracking blocking, phishing protection, and similar privacy-oriented features. However, if you want true anonymity, we suggest you employ a powerful Private Internet Access VPN – it can encrypt all the traffic that comes and goes out of your computer, preventing tracking completely.
Lost your files? Use data recovery software
While some files located on any computer are replaceable or useless, others can be extremely valuable. Family photos, work documents, school projects – these are types of files that we don't want to lose. Unfortunately, there are many ways how unexpected data loss can occur: power cuts, Blue Screen of Death errors, hardware failures, crypto-malware attack, or even accidental deletion.
To ensure that all the files remain intact, you should prepare regular data backups. You can choose cloud-based or physical copies you could restore from later in case of a disaster. If your backups were lost as well or you never bothered to prepare any, Data Recovery Pro can be your only hope to retrieve your invaluable files.
