Spyware is a type of malware that can infect your Mac and steal your personal information, track your online activity, or even control your computer. It can be difficult to detect, but there are a few things you can do to check for spyware on your Mac.
One of the most common signs of spyware is a decrease in your Mac’s performance. If your Mac is running slowly, freezing, or crashing frequently, it could be a sign that you have spyware installed. Other signs of spyware include unexpected pop-ups, changes to your browser settings, or new toolbars or extensions that you didn’t install.
