I suspect that this supposed “virus” is coming from the Apple update and that it is just a pre-installed file that is created and runs every time the OS is booted/rebooted.
Avast for mac os x how to#
So I have no clue where this has came from to be honest and I have no clue how to get rid of it. I checked all of my chrome extensions and nothing is out of order, I haven't downloaded anything special within the past week, besides the new Mac operating system (macOS High Sierra 10.13.1). My Avast runs full system scans every week, so this just recently became an issue this week. So if something is mining in the background, I can't tell at all. My CPU is running below 30%, my RAM is generally below 5GB (installed 16GB), and my network hasn't had any processes sending out/receiving large amount of data. I've been monitoring my CPU usage, Memory, and Network and I haven't seen a single odd process running. I researched the file path and cryptonight and found out that cryptonight is/can be malicious code that can run in the background of someone's computer to mine cryptocurrency. I want to avoid wiping the laptop and re-installing everything, so that is why I am here. Therefore the virus is re-creating the file every restart of the laptop. So I decided to let Avast put it in the virus chest, restarted the laptop, and again the file was in the same location again.
The file reappeared in the same location.
I found nothing, until I restarted my macbook pro today.
So, after deleting the file I did several more full system scans to check to see if there were any more files. The file's location is : /private/var/db/uuidtext/7B/BC8EE8D09234D99DD8B85A99E46C64Īvast categorizes the infection file as : JS:Cryptonight Yesterday I ran a full system scan using my Avast antivirus software and it found a infection file.
