    Hi, I don't want to be a stinker or anything. I also used mac for years. I recently did a system reinstall because of too many kernel panics (once a week). Then I was very careful with the newly installed system, which is the latest Mojave btw. I tried to only install apps from mac app store. Other than that, I have only "avast, "Calibre"(an app for managing ebooks, which Ive used for years) and "bluetooth explorer" (for tuning audio codes for my bluetooth speakers).
    Then today, my full system scan gave a warning of virus. I was really surprised by that considering how careful I have been. I dont think I can be even more careful than that. My question is, whether it is a false positive. Should I delete it? I really have no knowledge in this. Maybe someone can help. Thanks in advance!

    The path is located in what appears to be cache for Apple's App Store.

    When I google the search terms MacOS Cyberbyte-D PUP the following appears near the top of the list:
    https://discussions.apple.com/thread/250491502

    Based on this, I would say it's a false positive.

    The Avast forums might be a good place to ask about more details, rather than waiting for a random MacRumors user to post.

    I use software from anywhere, including "shady" sources, and never worry about "viruses" -- because there has NEVER been A SINGLE Mac "virus" discovered "in the wild".
