If you’re thinking of purchasing a used Mac^® computer, you may naturally wonder whether it’s immune to viruses and malware. While Apple® products have a certain sterling reputation where problems like these are concerned, the simple answer is that they can be vulnerable, even if it's far less so than the average PC. Here’s a closer look at these issues if you’re in the market for a device or need to bring your current device in for computer repairs.

Viruses

As a type of malware, viruses typically infect your device if you download a malicious program, click on a suspicious link, or install a harmful plugin or application. Usually, third-party browser plugins, such as Flash or Java, are to blame. A common scam known as a Trojan horse is another common threat. This is a seemingly normal and helpful program that appears legitimate at first, but when it’s clicked or downloaded, it allows a virus to infect your device and may provide an outsider with access to your system. 

So-called “macro” viruses can also impact your used Mac computer. These develop when you open a file that’s infected with certain macros, which are written in the same language used in legitimate software. These attempt to run codes that perform harmful functions on your machine, such as corrupting files and data, reformatting hard drives, and inserting unwanted images.

Other Types of Malware

Spyware is a common type of malware that’s used to track everything you do online. It runs in the background while you browse the internet, send emails, make purchases, and input your personal information. Another threat is adware, which causes the telltale pop-ups that typically alert users to a problem. 

Among the more threatening problems is ransomware, which essentially breaks into your computer and takes possession of it. It may prevent you from using it entirely and even produce a ransom note demanding some form of payment in exchange for resumed access to your device. 

How to Detect Problems

Fortunately, there are several common signs that indicate a problem with a Mac computer. It may operate slowly, crash frequently, neglect to start up, or become extremely hot to the touch. You may also find files, programs, or applications that you never installed. Pop-up windows may thwart your online browsing abilities, and you might be prompted to download new programs.

Running antivirus software is an effective way to not only detect and remove viruses and malware but also help prevent future problems. You should also be mindful of your online habits. Avoid downloading or clicking anything that’s questionable or unfamiliar anywhere online or in an email.
