- How To Disable Avast On A Mac For A Specific Website On The Internet

- Global Whitelist – Exclude Specific Website/URL from All Avast Scans. Go to ‘Avast shields control‘ » ‘Disable for 10 minutes‘ » confirm; Go again back to. These instructions are for PC users, not Mac users. The Mac UI is radically different to the PC – there is no way to do what the article/instructions say.
- Our free Mac antivirus protects on 3 fronts. Malware isn’t the only threat to your Mac. Malicious websites and vulnerable Wi-Fi networks can also jeopardize your safety. Avast Security provides essential free protection against all 3 threats, and our new Pro version goes the extra mile to expose Wi-Fi intruders and stop ransomware.
- Here are 3 simple steps to disable/turn off Avast 2018 (temporarily or completely). You can apply these steps for all Avast antivirus products (Pro Antivirus, Free Antivirus, Avast Premier or Internet Security).
To bypass Avast and visit a blocked website, you'll need to disable the Web Shield module or add the website to your Exclusions list. Some websites can be dangerous, so your computer and data are. I'm having a problem with Firefox for a while now and I thought some of you could maybe help me. Firefox just won't work properly if my antivirus is still enabled. As soon as I disable my Antivirus completely it starts working.
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 :
So, after deleting the file I did several more full system scans to check to see if there were any more files. 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.
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.

Pretty 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/
) 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:
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.
Avast free mac security reviews. 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? 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? 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:
Hello, I'll just add a bit more information.
https://keenspecialists255.weebly.com/avast-or-malware-bytes-for-mac.html. 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.
(The 'rude' texts are probably just names of malware.)

If your avast antivirus fails to update automatically, you may need to perform a manual update. If the computer to be updated cannot connect to the Internet, you will need a USB flash drive and a separate computer that is able to connect to the Internet.Step 1
Visit: http://www.avast.com/en-us/download-update on an Internet connected computer and select download by the update for the version of AVAST that you currently have installed. For most residents this will be “avast! VPS update for version 2014”. You can find out which version of avast you are currently running by launching the application, clicking on the help tab on the left and then selecting “About Avast”.
Step 2
After the file has finished downloading, it should remain in the bottom download bar of your browser
Avast extension safari. Chrome
Internet Explorer
Firefox
If this is the computer to be updated, simply click the file in Chrome or Firefox to launch the manual update, or select run if using IE. Select “Run” once again if prompted whether or not you would like to run the file. Simply follow the instructions given by the updater to complete the process.
Step 3
If the computer to be updated is not the computer you downloaded the update on, you will have to navigate to your download folder (usually located in C:Users”username” Downloads), locate the file (titled “vpsupd”) and move it onto a USB flash drive. Once you have done so, plug the USB flash drive into the computer to be updated, run the vpsupd file and follow the instructions given on screen.
