I have a 2013 MacBook Air which is overheating, I can’t figure out why. I checked everything.
However it was none of those things. Activity Monitor CPU use is high but I can’t understand why.
I’m thinking maybe my Mac has a virus. Can anyone recommend any good antivirus programs to check?

Mine has suddenly started doing the same thing. I just got it a couple months ago.

Your Mac can overheat for many reasons, it doesn’t have to be a virus. It’s especially common with rather old Macs like yours. Before you go looking for a cleaning software I suggest you try a few other things:
Unload your processor. Running many apps at the same time burdens your CPU – if its load is more than 70%, you’re going to have all sorts of problems, including overheating because the fan has to work faster to create a stronger airflow. To check your CPU load, go to Applications → Utilities → Activity Monitor → CPU. Quit all the processes with the highest percentage of CPU;
An obvious one would be to close extra tabs and heavy apps;
Don’t use your Mac on soft surfaces as it blocks the cooling fans and makes them work extra hard, ultimately overheating your laptop;
Check if anything’s wrong with your fan by running a hardware diagnostic. You can do that by restarting your Mac and, while it’s booting, holding command + D. This launches an Apple hardware scan. You will be shown the results when the testing is over – look for an error code starting with PPF, which indicates fan issues. Unfortunately, in this case your only option is to take the computer to a service centre.
