Nothing Deletes the JS:cryptonight Need Some Help Please

Sorry to bother you again Gary, but there seems to be lots of people having problems with what I asked you about earlier, it called the
JS: Cryptonight, I have tried multiple scans with different antivirus, AVG, AVAST, and both find it, and you can’t get rid of it, you can place it into quarantine and do a reboot, but when you scan its there again, /private/var/db/uuidtext/7B/BC8EE8D09234D99DD8B85A99E46C64.
above is what it finds and know matter what its stays,, I know you are a clever and wise man and I thought you could put minds at rest, and I know that apple have just had a security update,

    From what I can tell, this is a false positive. In other words, it is a bug in the Avast software that thinks you have something called “JS:Cryptonight” when in fact you don’t. It seems to think that this file is a part of that malware, when it is just a legitimate part of the OS.

    So no matter how many times you try to remove it, macOS will simply recreate the file and Avast will once again incorrectly assume it is part of malware.

    Here is a forum post by someone at Avast: https://forum.avast.com/index.php?topic=211215.msg1432713#msg1432713.

    Thanks Gary, but it looks like a sickness that a few antiviruses have caught.
    Cheers.

    Graham: Note that Avast and AVG are the same company. They probably both use the same malware definitions, and perhaps some of the same detection code.

    IMAC(Retina 5K, 27-inch, Mid 2015)…I was using avast too and had the same problem with JS Cryptonight on scan then to quarantine…reboot and its back. At same time I frequently had massive lag problems or freeze. In activity monitor it shows ..kernel task..which is actually your operating system…. running at 300%+. So no wonder the freezes. It is def. not benign and I cannot get rid of it. I have even done a total wipe/reinstall 5/6 times now.. It is someone using your cpu…Plz help someon

    steve: Read my initial reply above and look at that link. If you have something wrong with your Mac, it is not this. It is a false positive, nothing more. Take your Mac to the Genius Bar and figure out what is really wrong. However, I suspect it could be more problems with your anti-virus software. This is one of the reasons I advise people not to use this kind of software.
