Encrypted files, ZIP archives, and system files which are in use often cannot be scanned. To view the non-scanned file details do the following: In the Avast program go to Reports and click Open next to the report details you want to view. In the scan report window right-click and choose Non-scanned.

Yesterday I ran a full system scan using my Avast antivirus software and it found a infection file. The file's location is :
Avast categorizes the infection file as :
The lack of experience Avast has shown in dealing with the Mac platform was very clearly demonstrated by the Avast representative whom made several obvious errors in their attempts to discredit Thomas Reed, Who has always been a trusted source of good quality technical information on Mac security. The Avast activation code can be used for much better protection and without full version, you cannot clean the viruses through deep scan. If you’re prepared to safeguard your pc system from the newest threats files, you’ll need an Avast anti-virus activation code 2018 program before you decide to scan your pc.
So, after deleting the file I did several more full system scans to check to see if there were any more files. Download paint net for mac. I found nothing, until I restarted my macbook pro today. The file reappeared in the same location. 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. Therefore the virus is re-creating the file every restart of the laptop. Avast for mac and kaspersky.

I want to avoid wiping the laptop and re-installing everything, so that is why I am here. 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've been monitoring my CPU usage, Memory, and Network and I haven't seen a single odd process running. 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. So if something is mining in the background, I can't tell at all. I have no clue what to do.
My Avast runs full system scans every week, so this just recently became an issue this week. 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). So I have no clue where this has came from to be honest and I have no clue how to get rid of it. Can someone please help me out.
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. But I am unsure since I only have one MacBook and no one else that I know that has a mac has updated the OS to High Sierra. But Avast keeps labeling this as a potential “Cryptonight” virus and no one else online has posted anything about this issue. Therefore, a common virus removal forum isn't helpful in my situation, since I've already attempted to remove it with both Avast, malwarebytes, and manually.

1 AnswerPretty sure there is no virus, malware or trojan at play and his is all a highly coincidental false positive.
It’s most likely a false positive since
/var/db/uuidtext/ is related to the new “Unified Logging” subsystem that was introduced in macOS Sierra (10.2). As this article explains:
The first file path (
/var/db/diagnostics/ ) contains the log files. These files are named with a timestamp filename following the pattern logdata.Persistent.YYYYMMDDTHHMMSS.tracev3 . These files are binary files that we’ll have to use a new utility on macOS to parse them. This directory contains some other files as well including additional log *.tracev3 files and others that contain logging metadata. The second file path (/var/db/uuidtext/ ) contains files that are references in the main *.tracev3 log files.
But in your case the “magic” seems to come from the hash:
Just check out this reference for known Windows malware files that references that one specific hash. Congratulations! Your Mac has magically created a filename that matches a known vector that has been primarily seen on Windows systems… But you are on a Mac and this filename is just a hash that is connected to the “Unified Logging” database system’s file structure and it is completely coincidental that it matches that malware filename and should not mean anything.
And the reason that specific file seems to regenerate is based on this detail from the above explanation:
The second file path (
/var/db/uuidtext/ Earth crisis neutralize the threat rar files. ) contains files that are references in the main *.tracev3 log files.
So you delete the file in
/var/db/uuidtext/ , but all it is is a reference to what is in /var/db/diagnostics/ . So when you reboot, it sees it is missing and recreates it in /var/db/uuidtext/ .
As for what to do now? Well, you can either tolerate the Avast alerts or you can download a cache cleaning tool such as Onyx and just force the logs to be recreated by truly purging them from your system; not just that one
BC8EE8D09234D99DD8B85A99E46C64 file. Hopefully the hash names of the files it regenerates after a full cleaning won’t accidentally match a known malware file again.
UPDATE 1: It seems like Avast staff acknowledges the issue in this post on their forums:
Wincc scada software. I can confirm this is a false positive. The superuser.com post describes the issue quite well - MacOS seems to have accidentally created a file that contains fragments of malicious cryptocurrency miner which also happen to trigger one of our detections.
Now what is really odd about this statement is the phrase, “…MacOS seems to have accidentally created a file that contains fragments of malicious cryptocurrency miner.”
What? Outlook mac settigs for avast. Is this implying that someone on the core macOS software development team at Apple somehow “accidentally” setup the system so it generates neutered fragments of a known malicious cryptocurrency miner? Vpn for mac avast review. Has anyone contacted Apple directly about this? This all seems a bit crazy.
UPDATE 2: This issue is further explained by someone Radek Brich the Avast forums as simply Avast self-identifying itself:
Download greys anatomy season 6. Hello, I'll just add a bit more information.
The file is created by MacOS system, it's actually part of 'cpu usage' diagnostic report. The report is created because Avast uses the CPU heavily during the scan.
The UUID (7BBC8EE8-D092-34D9-9DD8-B85A99E46C64) identifies a library which is a part of Avast detections DB (algo.so). The content of the file is debugging information extracted from the library. Unfortunately, this seems to contain a string which is in return detected by Avast as a malware.

I have a question that I can't find the answer to at the Avast Help areas.
I have an external hdd that I had copied files to from a second smaller external hdd. This morning I got a notice alert from Avast about a possible virus in one of my files on my W8 drive and it recommended a boot scan. This boot scan also automatically scanned the external hdd (the second one is no longer connected), and after removing the virus files from the W8 drive, it found a large number of .zip and .exe files on the external hdd that are corrupted. A few older files were from long ago and are now being reported as having old viruses in them so I instructed Avast to delete them. That's no longer an issue, but I'm wondering how to direct Avast to also delete the corrupted ones. I'm thinking they were corrupted during the copy process from one external drive to another somehow. I had started to write down the actual files as they appeared during the boot scan, but it got to be way more than I thought there would be. How can I run the scan again and direct it to delete only the corrupted ones? I've tried changing the settings in Avast within Windows but it didn't find anything wrong now. There are three file types for it to check (Virus, PUP, and Suspicious), but nothing about corrupt files. Would I have to do another boot scan (it took two hours)? I don't think they can be repaired since they are archived types that actually run the programs they go to, and the thought of clicking every single file on that drive (almost 350GB worth) to find each one and manually delete the file really isn't something I'm looking forward to doing unless I absolutely have to. Thanks for any suggestions or solutions... Comments are closed.
