A virus is a malicious software program that can infect and damage your computer. Viruses can spread through email attachments, downloads from untrustworthy websites, or even USB drives. If you think your Mac may be infected with a virus, there are a few things you can do to check.
One way to check for a virus is to use the Activity Monitor. The Activity Monitor shows you all of the processes that are running on your Mac, and it can help you identify any suspicious processes that may be caused by a virus. To open the Activity Monitor, press Command+Space and type “Activity Monitor.”
