![]() You can perform a deep scan of your entire system, a targeted scan of specific files or folders, a USB/DVD scan for removable media or a smart scan of just the most likely areas for a malware infection. Most of the features are centered around scanning for malware. Bitdefender, Intego and Kaspersky were all part of the June 2021 test as well and received a perfect 100% each, while Trend Micro scored 99.6% detection.Īvast Security for Mac: Security and privacy featuresĪvast Security for Mac offers antivirus protection that is on par with many of its paid competitors, but as you'll see, the full feature set is less robust. It has scored perfectly on the AV-Comparatives test since receiving a 99.9% detection score in July of 2017. Turning to AV-Comparatives, Avast Security for Mac successfully identified 100% of Mac malware threats. These were during the October-November 2018 (96.3%) and August-September 2020 rounds (98.6%). Intego Mac Security X9 and Kaspersky Internet Security for Mac had been tested in previous rounds, scoring 98.5% and 100%, respectively.Īvast Security for Mac also avoided any false positives in the latest round of tests, meaning that all detections of malware were accurate, but this was true of its competitors as well.Īvast Security for Mac has fallen short of detecting 100% of Mac malware threats in AV-Test's evaluations only twice since April of 2017. During this same round of testing, Bitdefender Antivirus for Mac (100%), Norton 360 Standard (100%) and Trend Micro Antivirus for Mac (100%) matched its perfect performance. In order to determine the overall efficacy of Avast Security for Mac's malware scanning, we relied on results from Germany-based AV-Test and Austria-based AV-Comparatives, two independent labs that conduct regular evaluations of major antivirus apps and services.ĭuring the March-April 2021 testing by AV-Test, Avast Security for Mac detected 100% of Mac malware. Avast Security for Mac will also scan your entire network for potential threats.Īvast Security for Mac: Antivirus performance While its primary intent is to protect your Mac, Avast Security for Mac also scans for malware targeting Windows PCs so your Mac doesn't pass on a potential Windows threat over the local network, email or a file-sharing method.Īvast updates its virus definitions automatically at regular intervals, but you can force an update if you prefer. It also leverages Avast's significant user base of 450 million devices to help identify new threats quickly. ![]() The other is a feature that actively monitors your home Wi-Fi network and notifies you as soon as anyone joins your it, catching neighbors the moment they gain entry to your network.Īvast Security for Mac supports any Mac running macOS 10.11 (El Capitan) or later.Īvast Security for Mac: Antivirus protectionĪvast Security for Mac relies on signature-based malware detection to identify potential threats to your Mac. The most crucial is ransomware protection, which acts to protect your photos and other personal files from being encrypted or changed without your permission. I prefer BitDefender because it eliminates a lot of potential interoperability problems, and is highly rated in the various AV tests.There is an Avast Premium Security tier, available for $70 per year for a single Mac, that introduces a couple of features appealing to those looking for enhanced security. BitDefender gets automatically called when a file is opened, so it has a chance to scan it. However, whenever I open an attachment (the main risk with new mail) Thunderbird creates a temporary file containing the attachment and passes the location as command line arguments. It doesn't "know" about email so it doesn't attempt to scan new mail. I've used Avast in the past but now use the free version of BitDefender. Plenty of people use Avast with no problems, so I'd assume you are running into some sort of configuration specific bug. If that doesn't help I suggest you also try using a different antivirus scanner. Its possible you ran into this bug only because Thunderbird was already running when Avast hacked Thunderbird's certificate store so that it can later on do a benign man in the middle attack and scan mail sent over a secure connection. Try exiting Thunderbird, uninstalling Avast, and re-installing it. However, its quite possible the problem will re-appear. ![]() When you restart Thunderbird it will be rebuilt. I suggest you start by exiting Thunderbird and deleting the "global-messages-db.sqlite" search index file.
