Thanks to a smaller market share, Macs are not as susceptible to malware infections as their Windows counterparts. However, it’s still possible to find your Mac infected with malware. This often happens to users that aren’t careful about where they download files from, or users that blindly click through installation prompts for free software and find themselves loaded up with free trials of software they don’t need. If you want to remove malware, viruses or other undesirable programs from your Mac, the following will show you how.

Malware, short for “malicious software,” is any type of program that interferes with the operation of a user’s computer or acts against the desires of the user. According to Wikipedia, this includes “computer viruses, worms, Trojan horses, ransomware, spyware, adware, scareware, and other malicious programs.”

Most malware is installed without the user’s consent or knowledge. However, thanks to misleading file downloads or false advertising, users sometimes intentionally install malware. This happens most frequently with fake anti-virus programs like MacDefender. It looks like a useful application, but you aren’t aware that it is hijacking your system and slowing down your computer. And while bad actors like this typically get quickly removed from the market place, there’s new ones popping up frequently.

These undesirable programs are called “Potentially Unwanted Programs,” or PUPs. Browser toolbars often fall into this category. It also includes other spammy or intentionally misleading applications. Users might want to keep them, but there’s a good chance they’re causing damage to your system without your knowledge.

Not every slow computer is suffering from a malware infection. Less-experienced computer users will often chalk up all manner of system problems to “viruses” and “malware.” Of course, this is sometimes to blame. But, more frequently, users have done a poor job maintaining their machines. As a result, there are sometimes other steps that need to be taken to return your machine to good working order.

Just because your malware scan comes up negative doesn’t mean your computer is working perfectly. If your Mac is still running poorly, you might need to do a little clean up. While Macs require less maintenance than Windows machines, keeping your hard drive full to the brim or running too many applications will still slow you down. As much as Macs might “just work,” you still need to keep your machine in good working order.

1. When the scan is finished, a window from Malwarebytes will pop up to notify you of the scan’s results. If this window doesn’t appear, you can reach it by clicking “Open Malwarebytes” in the menu bar and then clicking “Scan” in the left side of the Malwarebytes window.

It’s true that Mac malware is not as prevalent as Windows malware and viruses. However, that doesn’t mean none exist. Enterprising hackers looking to target a vulnerable user base could do worse than Mac users. Considering the cost of hardware, many Mac users might have deeper pockets that Windows users, making them ripe targets for ransomware, data theft or corporate espionage. As a computer-using citizen, it’s your responsibility to protect yourself against even unlikely attacks. And especially when it’s so easy to do!

With Malwarebytes you can scan your Mac for malware as frequently as you would like. If you want real-time, proactive protection, you can get the Malwarebytes Premium subscription tier. This enables automated, round-the-clock monitoring for suspicious files. If you frequently download or install software, that might be worthwhile. And for users that download from sites like PirateBay, reliable malware detection is a must-have.
