During , Mac users saw the harsh truth behind the myths about the security of Mac environments: In early , the Flashfake botnet was discovered — consisting of , computers that were all running under Mac OS X.

Throughout , cybercriminals repeatedly used Mac malware when launching targeted attacks. Some viruses, including the novel coronavirus currently driving outbreaks around the globe, have lower fatality rates, but still pose a serious threat to public health as we don't yet have the means to combat them.

Here are the 12 worst killers, based on the likelihood that a person will die if they are infected with one of them, the sheer numbers of people they have killed, and whether they represent a growing threat. According to the World Health Organization WHO , the Marburg virus was first identified by scientists in , when small outbreaks occurred among lab workers in Germany who were exposed to infected monkeys imported from Uganda.

Marburg virus symptoms are similar to Ebola in that both viruses can cause hemorrhagic fever, meaning that infected people develop high fevers, and bleeding throughout the body that can lead to shock, organ failure and death, according to Mayo Clinic.

The first known Marburg virus outbreak in West Africa was confirmed in August The case was a male from south-western Guinea, who developed a fever, headache, fatigue, abdominal pain and gingival hemorrhage. This outbreak lasted for six weeks and, while there were high-risk contacts, only one case was confirmed, according to Reuters.

In , the first known Ebola outbreaks in humans struck simultaneously in the Republic of the Sudan and the Democratic Republic of Congo. Ebola is spread through contact with blood or other body fluids, or tissue from infected people or animals. The known strains vary dramatically in their deadliness, Elke Muhlberger, an Ebola virus expert and associate professor of microbiology at Boston University, told Live Science.

The outbreak underway in West Africa began in early , and is the largest and most complex outbreak of the disease to date, according to the WHO. In December , the Ervebo vaccine was approved by the U.

Food and Drug Administration. This vaccine helps to defend against the Zaire ebola virus and a global stockpile became available from January Although rabies vaccines for pets, which were introduced in the s, helped to make the disease extremely rare in the developed world, this condition remains a serious problem in India and parts of Africa.

Infection from this virus develops after a bite or scratch from an infected animal. This can result in damage to the brain and nerves.

In the modern world, the deadliest virus of all may be HIV. Amesh Adalja, an infectious disease physician and spokesman for the Infectious Disease Society of America. An estimated 32 million people have died from HIV since the disease was first recognized in the early s. Powerful antiviral drugs have made it possible for people to live for years with HIV.

In , there were , HIV-related deaths worldwide. Once it's in your system, the malware changes DNS server settings that allow attackers to route traffic through malicious servers. That's how they gain your sensitive data. MaMi is also capable of taking screenshots, downloading and uploading files, executing commands, and generating mouse events. The Hacker News provides instructions on how to identify the virus in your system:.

This piece of Malware is dangerous since it's signed with an Apple-authenticated developer certificate. Since April , Apple has revoked the developer certificate and updated XProtect. However, it remains one to watch out for. The preventive solution has not been found yet since the nature of it remains unknown. So while Apple has been working on finding a way to detect and remove it, the newer and more sophisticated versions might still exist in the wild.

While its name suggests it could be a useful app, MacDownloader is a very nasty piece of malware programmed to attack the US defense industry. By clicking on the alert and entering your admin password, MacDownloader obtains sensitive data and sends it to a remote server.

It was bundled with the torrent client Transmission version 2. Once documents and data files are encrypted, KeRanger demands payment in bitcoin for the malware to be removed. The Goto fail bug was a bit of an embarrassment for Apple because this security flaw was a result of its own doing. Such glitch put communications sent over unsecured Wi-Fi the hotspots you use at the mall and in coffee shops at risk, allowing hackers to abduct almost anything they want.

Apple managed to fix the issue on macOS, but it certainly makes you think twice about how you browse the web in public places. In January , it was announced that there was a flaw in Intel chips used in Macs, giving rise to the dastardly duo of Meltdown and Spectre.

Meltdown and Spectre affect all Mac systems, but Apple insists there are no known exploits currently impacting customers. It was discovered by software developer Lemi Orhan Ergin. The bug allows anyone to gain root access to a system by leaving the password field blank.

Done, they're in! Scary, right? Curious about how you can spot a virus on your Mac? With other malware, however, the infection is much harder to track. There are two ways that you can do this: manually or with my personal favorite app, CleanMyMac X. If it's a downloaded file, go to the Downloads folder and search for.

Once it was discovered, Apple went in and shut down all the infected copies of Xcode. Apple eventually replaced the classic Mac operating system with the new Mac OS X, which came with built-in malware security measures. For instance:. There are ways to bypass them, and they don't block or detect all threat types. How do you know if your Mac has a malware infection?

If you think it's infected, try our free virus scanner , and look for such clues as:. For example, viruses and Trojans are two specific types of malicious software, both of which are malware.

The fact is, viruses are much less of a thing today, largely because there are far easier ways to infect Macs with Trojans, worms , spyware, and ransomware. This puts Mac users at higher risk of getting infected with something nasty. Pay particular attention if the domain ends in an odd set of letters, i. Remember, you are your own first line of defense, so stay vigilant.

Beware of unsolicited email attachments and software from untrustworthy websites or peer-to-peer file transfer networks. Finally, install a Mac cybersecurity or anti-malware program from a reputable vendor.

This will protect you from malware that makes it past your good cybersecurity habits. If you do take a hit, hit back by downloading Malwarebytes for Mac , run a scan, and rest easier. It zaps and continues to block malware. It can even recognize when new threats appear to be similar to the signatures of previously identified threats, providing protection against new, unidentified threats zero-day. Avoid opening unsolicited email attachments or downloading software from untrustworthy websites or peer-to-peer file transfer networks.

Keeping security in mind can go a long way toward keeping you safe from some online threats, but not all of them.
