Today's best Avira Free Antivirus for Mac deals
The abundance of solid free antivirus solutions available on the Mac means you can be choosy about which one you download. For example, while we can appreciate Avira Free Antivirus for Mac for its relatively low impact during passive scanning when it's running in the background, that's not enough.
Unfortunately, while Avira's malware-detection score is good, it's not enough to make it the best antivirus for Macs. For Mac protection without any expense, we recommend Avast Free Mac Security; if you can afford $40 per year, then Kaspersky Internet Security for Mac is an even better bet for its perfect detection rates and parental controls.

Costs and What's Covered
As its name declares, Avira Free Antivirus comes without any price tag. For those who may want technical support and other perks, Avira also offers Avira Antivirus Pro ($44.95 per year), which bundles in software for both Mac and Windows, and the Avira Prime ($9.99 per month) subscription, which gives you access to all of Avira's paid products.
Avira Free Antivirus for Mac supports the most recent two editions of macOS, which at the time of this writing were macOS 10.12 Sierra and OS X 10.11 El Capitan.
Antivirus Protection
Avira protects Macs using traditional signature-based malware scanning, as well as behavioral monitoring that scans for patterns commonly seen in dangerous and unwanted files.
Like most other antivirus products, Avira Free Antivirus for Mac constantly updates its malware-signature database, which receives information from the 100 million users of the company's Windows, Android and Mac software. Avira stops PC malware on Macs from spreading across external drives and networks.

In addition to routine background scans, Avira offers both on-demand and scheduled scans, and scans unopened archive files such as ZIPs.
Antivirus Performance
Austria's AV-Comparatives evaluation lab tested Avira's malware-detection skills and found it offered high, but not perfect, protection.
In AV Comparatives' July 2017 studies, Avira Free Antivirus for Mac detected 99.1 percent of malware, which translates to catching 681 pieces of malware and failing to detect six. In comparison, Avast Free Mac Security and AVG AntiVirus for Mac caught 99.9 percent of malware (686 out of 687).
Among paid options, Bitdefender Antivirus for Mac and Kaspersky Internet Security for Mac, detected 100 percent of both Mac and Windows malware.
Security and Privacy Features
As is often the case with free antivirus solutions, Avira Free Antivirus for Mac is light on extras. Although it comes with a firewall (disabled by default), macOS has its own already. A USB scanner tool can be added on by upgrading to Avira Pro.
While Avira does offer its SafeSearch Plus tool (free) to help you stay away from infected sites, it doesn't install the browser plugin during installation.
Performance and System Impact
Avira Free Antivirus for Mac had a mixed impact on system performance. We assessed the performance hit with our custom OpenOffice benchmark test, which matches 20,000 names and 20,000 addresses on a spreadsheet and measures how long it takes to finish the task. Our test machine was a Late 2013 MacBook Pro with Retina Display, with a 2.6-GHz Core i7 CPU, 8GB RAM and 70GB of data stored on a 512GB SSD.
After we installed Avira Free Antivirus for Mac on our MacBook, the OpenOffice test finished in an average of 2 minutes and 24 seconds, 1.5 seconds longer than the same system took before installation. That's a passive system hit of 1.1 percent, on the lower end of the range we found among the eight products we reviewed.

During a full-system scan, the OpenOffice test finished in 2 minutes and 41 seconds, signifying a performance dip of 18.25 percent, the highest we saw. AVG's 12.1 percent was the second highest we recorded, and Kaspersky's 4.5 percent the lowest.
During Avira's quick scans, the OpenOffice test finished in 2 minutes and 37 seconds, which indicates a system slowdown of 10 percent. That's on the high end.

Avira Free Antivirus for Mac's full scans completed in an average of 30 minutes and 13 seconds, which falls in the middle of the times we recorded. By contrast, the longest time we saw was 72:45 (Kaspersky), while the shortest was 1:25 ( Bitdefender). The average for all eight Mac antivirus products tested was 36:30.
Interface
Avira Free Antivirus for Mac offers the same clean, modern look you see in many third-party Mac apps. Its main window presents a system status (Protected, typically) along with buttons for starting scans, scheduling scans, your quarantine, system activity and your license (more on that later).
Clicking New Scan gives you the option for a Quick scan or a full system scan, as well as a button to start the scan. While we prefer one-click scans, this arrangement is pretty decent and consolidates the screens into a pop-up menu.
The scheduled-scan page brings a drop-down sheet where you can name the days and times scans should run as well as their type (full, quick) and frequency (weekly, daily).
The Quarantine button brings you to a view of any files Avira has flagged as dangerous and set aside, while the Activity button shows you a list of your most recent scans. Clicking License lets you enter the Activation Code that an Avira Pro or Avira Prime membership comes with.
Clicking the option-toggles icon in the menu bar brings you to the Real-Time Protection screen, which allows you to disable file protection (don't do it) and enable Avira's Firewall. The profile icon brings you to what I'd call the About screen. Here you can see version info and click links to the Avira Community support page, product videos and other meta-level web pages.
Installation and Support
After you click Download, the superlight disk image file containing Avira Free Antivirus' installer will download. After opening that, the rest of the files are downloaded. In total, it took less than 3 minutes to complete the process.
Avira's customer support is limited to its paid customers, so you'll need Avira Pro or Avira Prime for that. In lieu of that, you can search Avira's FAQ documents and community message boards.
Bottom Line
Avira Free Antivirus For Mac continues to be a good option for protecting your Mac from malware; unfortunately, that's not enough. Sure, we like its easy-to-use interface, but its malware protection scores aren’t as good as what AVG Antivirus for Mac and Avast Free Mac Security offer. Avast also causes less system impact than Avira, which makes it our top free choice.

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.
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.
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.)
