my desk top computer has a virus

You are not addressing Apple here. We are end users like you. There are no Mac viruses in the wild, and 99+% of such questions here are triggered by fake popups or scam phone calls.

Please tell us why you think you have a virus. Then we can be more specific.

Jack-19 is correct, also there are no viruses in the wild for Mac OS, however users can download other types of malware that Malwarebytes can help remove. Just get the free version as suggested.

Please do not install any third party antivirus apps, they will NOT add any additional layers of security for Mac OS!!!!!

Is there a specific reason you think your machine has some malware?

Hi koolmike,

If you are concerned about malware, get the free version of Malwarebytes from Mac and run it. ONLY download from the official Malwarebytes webpage.

Cheers,

Jack
