How to Detect that The Computer Is Infected
If your Mac is infected, it will work slower than usual in the first place. In a majority of cases, viruses do their best to remain undetected. If the cybercriminals are using malware to steal data from your computer, they will keep it undetected as they don’t want you to detect it.
The unusual behavior of your computer can give clues that the device is infected. The fan will run continuously; the device will run slower or stop responding and start rebooting abruptly.
If you find anything that you have not installed, such as software, a plugin, toolbar, or a browser extension, a malicious program can be the culprit. Moreover, if you detect that your system settings have changed mysteriously, malware can be the reason.
