How To Get Rid Of Malware On Mac: Removal Guide

There’s no doubt that for a long time, Mac users didn’t have to worry about viruses and malware. One of the biggest reasons for this is that Apple has written software specifically to control which programs can be run on their devices, named Gatekeeper.

There is also another piece of software called XProtect, which runs in the background on Macs and constantly scans for malware. This is highly effective, as Apple does a good job of keeping its list of malware and other malicious programs up to date.

The previous lack of viruses and malware is part of the reason Macs have become so popular and a status symbol. But now the popularity of Macs is part of the reason that new types of malware are developed every day. According to independent security institute AVTest, there were 670,000 pieces of malware targeting macOS in 2020. This is more than 56,000 pieces of malware per month. In addition, there were 48,000 pop-up ads identified.

Thankfully, this figure doesnt seem quite as high in 2021. In the year up to November, only 17,210 pieces of malware have been found, or 1,434 per month. This may be due to security patches, cleaner software, or increased user awareness of the threat of malware.
