How We Tested
To find the best antivirus for Mac desktops and laptops, we evaluate ease of use, interface and performance impact, we installed each AV program on the same Late 2013 MacBook Pro with Retina Display running macOS 10.12 Sierra. It was powered by a 2.6-GHz Intel Core i7 processor and had 8GB of RAM and 70GB of data stored on a 512GB SSD.
We conducted our own tests in July and August 2017 based on how much each antivirus product affected our laptop's performance. To do this, we used our custom OpenOffice benchmark, which matches 20,000 names and addresses in a spreadsheet. We measured how long it took to run a quick scan and a full scan while the laptop crunched numbers in the background.
We assessed how easy each program was to use and the number of useful extra features it offered (including free add-on software). To gauge how effective each package was at stopping malware, we used the results of evaluations conducted in May 2017 by AV-TEST, a well-regarded independent product-testing lab in Germany, and results from other tests conducted in July 2017 by AV-Comparatives, a similarly well-respected firm in Austria.
Best Mac Antivirus
Kaspersky Internet Security for Mac
Reasons to Buy
Minimal system impact
Reasons to Avoid
Kaspersky Internet Security is the best antivirus for Macs because it offers both the lowest system impact and some of the best malware-detection rates recorded. It even provides extra security features, including parental controls and options to lock down your webcam and stop websites from tracking your browsing activity. If you're willing to pay to protect your Mac from malware, Kaspersky Internet Security is the best option available.
Best Free Mac Antivirus
Avast Free Mac Security
Reasons to Buy
Excellent malware protection
Password manager included
Reasons to Avoid
Avast Free Mac Security caught 99.9 percent of all malware, packs in a password manager, barely leaves a smudge on system impact and doesn't charge a dime. If only it caught 100 percent of malware, as Kaspersky did.
Bitdefender Antivirus for Mac
Reasons to Buy
Ransomware protection
Parental controls
Reasons to Avoid
$38.99
Bitdefender Antivirus for Mac is one of only a few solutions we tested that offers perfect malware detection. Further, its modern, streamlined interface places on-demand scans front and center. Bitdefender has dropped from first place, though, because its system-impact scores don't match the flawless marks posted by Kaspersky.
Norton 360 Deluxe
Reasons to Buy
Reasons to Avoid
Noticeable system impact
Norton 360 Deluxe may offer excellent protection, but it charges more (after the first year) than its competitors do, without offering as many perks. Norton AntiVirus Plus offers similar protection for a single Mac, but with fewer perks. Still, both have always-on-call customer support.
AVG Antivirus for Mac
Reasons to Buy
Free
Reasons to Avoid
Comparatively high background impact
AVG Antivirus for Mac
If you're looking for the best antivirus for Mac without having to pay, AVG AntiVirus for Mac is not too shabby, with its 99.9 percent detection rate and easy-to-use design. Unfortunately, other free competitors provide extras (Sophos with parental controls, Avast's password manager) that AVG does not.
Best for Families
Sophos Home
Reasons to Buy
Remote manageability
Low system impact
Reasons to Avoid
With Sophos Home for Mac's simple interface and low system-performance impact, you'll barely realize the program is shielding you until you need it. Anyone with young children at home will find Sophos' parental controls useful, as they allow for remote scans and checks, and let you block sites by category. Sophos even keeps a log of when users try to reach banned pages. This program's major drawback, though, is its lackluster malware-detection rate.
Avira Free Antivirus for Mac
Reasons to Buy
Solid malware protection
Reasons to Avoid
Once our favorite, Avira Free Antivirus for Mac is no longer the best antivirus for Mac. That's because it is a hair shy of perfection in its malware detection, and fell behind in system-performance testing, earning some of the higher performance impacts recorded.
McAfee Antivirus Plus
Reasons to Buy
Familiar user interface
Reasons to Avoid
Unproven detection rates
McAfee® AntiVirus Plus
While McAfee's unlimited licenses mean you can support a whole family of Macs (and PCs and Android devices, too), this program's lack of special features (for a paid version) make it hard to recommend. Further, we don't have malware-detection testing scores for McAfee, so its protection powers are unproven.

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.Avast For Mac Antivirus Free Download 2016
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.
