Unfortunately, with the advances in technology and complexity of attacks, no one is safe. According to research by security firm McAfee, there is a 700% jump in the number of malware threats to Mac OS systems compared to the previous year. Statistics indicate that the fourth quarter of 2016 saw 460,000 malware instances affecting the Mac OS. Research says that the primary reason for the increased incidents has been attributed to the increase in adware bundling on the Mac OS. With increasing attacks of Malware, it’s important to know how to detect and prevent harmful attacks. Follow these tips to keep your device protected. **How to detect malware:** Does your computer seem to be running slow? This may be due to malware. By tracking your activities, sending unwanted ads, and crashing programs, your computer may be nearing a crash caused by malware. Too many ads aren’t good. If you are receiving multiple unwanted ads, error notifications/messages, or even anti-virus software ads, odds are your computer is already infected. If your computer’s settings are changing without your permission, then it would be a smart move to begin looking into some anti-malware software. Malware has the ability to change the settings on your homepage, toolbar, and search page. Research different malware detection software and install the best fit for your device. With this software, it is much easier to identify infectious sources. **How to prevent malware:** 1. Install anti-virus/anti-malware software. This is the best way to keep your device secure. These types of software can prevent and block malware. 2. Avoid suspicious links and attachments. They can look legitimate, so always be careful. Here are some examples of extensions that are typically associated with infectious Malware links: *.exe, .scr, .lnk, .bat, .vbs, .dll, .bin, and .cmd*. Find more [here](https://www.techwalla.com/articles/list-of-all-file-extension-viruses). 3. Be cautious when downloading new software. Malware attackers are professionals in disguising their viruses as credible sources, so always review and research what software you’re downloading and make sure it’s a valid source. 4. Limit what your applications can do. By giving programs limited access, it’s easier to find Malware when you can see what program is making changes on your device.
