    You are learning Mike, you are learning. Tell him not to go to sites such as CNET, Softonic etc. which specialise in these little bundles of joy.
    Hang on to those original install discs like grim death! Using OS X.7 or later make a bootable USB thumb drive before running Installer!

    But they aren't *viruses*, just annoying malware (popups, ads, hijackers, etc) the the user installed (maybe didn't know it, but he/she did). I know it's difficult to conceive it, but right now there are NO true viruses for Macs in the world. And the malware that is there is pretty benign, in the end. No data destruction, encryption, ransomware.

    And Harry's advice is dead on target. CNET, Softonic, Download.com, etc are all "bundling" those little packets of crapware with their "free" downloads.

    Mike as a PC technician can't seem to accept that Jake.

    That I am not sure of, I have cleaned malware which had slowed down the mac's performance.

    I have seen malware affect the browser, through either hijacking it, or adding ads, or multiple links to other ads, or even ads that you cannot click away, but never any that slowed down the entire Operating System. And when I have heard mac users say, "I ran my antivirus and it found xx infected items," I have challenged them that I bet every one of those "infected" items was an email from a Windows user. So far, I'm batting 1000. There simply are NO viruses for macOS in the wild today. I run Ghostery to keep my browser going smoothly and occasionally malwarebytes.com's app and that's all I find I need. Onyx once a quarter, if that often, to clean up the logs/cache/other cruft that accumulates.

    What is much more likely to slow down the Mac are large log files, large cache files, full hard drives and low memory. Other than that, I've not seen anything which can affect the entire system. I'm surprised you found anything that slowed the entire Mac. May I ask if you remember what it was?

    I had run Malwarebytes and Adwcleaner and can't remember if I had also ran SAS but anyway point is, once all of those utilities had cleaned out what it had found the mac's performance was back to normal.

    Oh, ok, Mike. Those two remove malware, not viruses. There is a difference! Still no viruses out there for Macs, just malware that pops up ads, redirects the browser, etc. And yes, running those utilities will often speed up the browsing, but none of the malware slows down the whole machine. On the other hand, most AV software does impact overall performance of the machine because the application takes cycles and intervenes in just about every action. Since there are no viruses and the AV software doesn't stop the malware, it's generally considered both useless and undesirable. I do run Ghostery on my browser to block most of the ads, trackers, beacons, etc., and I run malwarebytes once or twice a year, just in case anything got through. Other than that, nothing.
