While many types of malware try to remain unseen, in addition to keeping up-to-date security software on your device, you can be on the lookout for some red flags that might indicate a malware infection: This is why it’s so important to have antivirus software that recognizes and helps remove malicious software. Malware that you might not realize is on your device could be capturing data as you log into online accounts, finding valuable personal information stored on your device, or even turning on your webcam without your permission. Just as different types of software perform different functions, so different types of malware can perform different jobs, whether they make themselves apparent or run on your device while hiding in the background. Unlike the old days, when malware like viruses often announced themselves by displaying messages or by giving your computer the “blue screen of death,” many types of malware today can hide without producing any tell-tale symptoms of an infection.

Unfortunately, bundled adware is becoming as bad on Mac OS X as it is on Windows.Some types of malware “announce” themselves, while others can hide on your device Apple has added some adware to the XProtect list, but adware is mostly not blocked. The list of malware is also very limited, with the XProtect file containing 49 definitions at the moment. But it doesn’t take care of cleaning up any existing infections and doesn’t check to make sure your Mac is clean in the background. XProtect is just a convenient way for Apple to blacklist individual pieces of malware.

It’s just looking for a handful of bad files Apple has specifically listed. Unlike other antivirus applications, XProtect doesn’t use any sort of advanced heuristics. It only checks downloaded files run through File Quarantine, which makes it similar to the SmartScreen feature on Windows. It’s designed to sit between your Mac and the web, preventing you from running a few known-malicious applications. RELATED: Mac OS X Isn't Safe Anymore: The Crapware / Malware Epidemic Has Begun

If you disable it, your Mac won’t update its XProtect file with the latest definitions from Apple.
Ensure the “Install system data files and security updates” option is enabled. To view this setting, click the Apple menu, select System Preferences, and click the App Store icon. Malware definition updates arrive through Apple’s normal software update process. Like other software updates on Mac OS X, these are enabled by default, but can be disabled. When you open a downloaded application, File Quarantine checks if it matches any of the malware definitions in the XProtect file. If it does, you’ll see a nastier warning message that says running the file will damage your computer and informing you which malware definition it matches. You can even open this file and see the list of malicious applications Mac OS X is checking for when you open downloaded application files. Back in 2009, Apple made File Quarantine also check downloaded application files against a list stored in the System/Library/Core Services/CoreTypes.bundle/Contents/Resources/ist file on your Mac.
