Kaspersky Antivirus is a very well-known antivirus that people have been using for many years. It can detect and remove all sorts of viruses and malware. It is also coupled with a built-in firewall that can keep you secure when you’re online.

CleanMyMac X is a trustworthy and known cleaning software that also comes with a malware removal tool. It also comes built-in with a monitoring tool called Malware Monitor. It acts as a gatekeeper by monitoring your mac in real time for the risk of spyware or any unauthorized presence.
Does Mac have built-in antivirus?
Yes, your Mac will have built-in antivirus software that scans your system and ensures that there are no known bad applications running in the background. Ideally, you would not require antivirus software, but it’s good to have one running on your system.
How can you see if someone’s spying on your Mac?
If someone is spying on your Mac, you will be able to get to know by noticing a few changes in your system’s performance. Your Mac would be slower than normal. Your Mac camera would turn on at random intervals which could mean that someone has access to your camera and can see you right now.
Another way to find out if your Mac has spyware is to run antivirus software on your system to detect if there are any unwanted applications running in the background.
