If you want install or run a program but it’s being blocked by Avast you can simply turn off Avast shields for a short period of time. For more information about turning off Avast or it’s shields, check our full guide ‘ How to Turn Off (Pause, Disable) Shields in Avast Antivirus 2018 ‘. 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.

They then pushed support in OSX onto 3rd parties, which means it didn't mean the requirements put forth by different levels of government as research qualifying machines. Next the first party version of GCC included in OSX had serious bugs show stopping bugs in the math libraries that never got patched up until Apple removed the included version of GCC. XQuartz was a community response to Apple never updating X11, or fixing many bugs. Letting the user install 3rd party programs IS NOT official support.

In very rare cases, Avast may detect and block some programsor website pages as a virus, although you know for sure it’s safe. These wrong detections are called false positives. If such false-positive detection prevails after the virus definitions update, you may want to exclude the detected software or website from the Avast scan.

This is a perfect fix when Avast is blocking one of your favorite programs, but you still want to run/allow it. In the past, Avast was blocking some of the most popular software (Steam for example) for a short period of time. To be fair false-positive detection happens basically to every antivirus on the market, it’s not just Avast.

Anyway, we strongly recommend scanning the file/webpage also through some other virus engines to make sure it’s really clean. For this, you can use a free online scanner VirusTotal. Sometimes you may think the file/URL are safe but they are actually infected and it’s not just Avast which is detecting them.

Quick Summary

1. Make sure the blocked file or webpage is not malicious by testing it at www.virustotal.com
2. Add it as an exception by going to Settings » General » Exclusions
3. Confirm by clicking OK

Read more detailed steps and other options including screenshots below.

In this guide, you will learn how, but we strongly suggest using exclusions only when you’re an advanced user. There are three basic types of exclusions/exceptions in the Avast Antivirus 2019:

• Global exclusion list of the folder/file/program/application from being scanned at all
• Global exclusion list of the website/URL from being scanned at all
• Exclusions in the specific shield (File System Shield, Mail Shield, or Web Shield)

Global Whitelist – Exclude Specific Folder/File/Program/Application from All Avast Scans

If you want to add the exception for the specific website, domain, or URL from being scanned by Avast, follow these steps. This is so-called Global Whitelist or Exclusion List.

1. Open the Avast user interface and go to ‘Settings‘ » ‘General‘
2. Find the tab ‘Exclusions‘ and add specific programs to the ‘File paths‘ tab
3. Added applications and/or paths will now be excluded from any Avast scanning

Adding File/Folder/Program Exception into Avast 2019

On the screenshot above you can see that application ‘FileZilla FTP Client‘ and ‘DAEMON Tools Lite‘ are excluded. Such exceptions also apply to all sub-folders on these folders as we have used ‘/*’ in the path.

Global Whitelist – Exclude Specific Website/URL from All Avast Scans

If you want to add the exception for the specific Avast shield, follow these steps.

1. Open the Avast user interface and go to ‘Settings‘ » ‘General‘
2. Find the tab ‘Exclusions‘ and add specific websites or URLs in the ‘Urls‘ tab. Please note ‘http://’ will be added automatically, so if you want to exclude Yahoo, just type yahoo.com. Please note you need to differentiate between ‘http://’ and ‘https://’
3. Added websites/URLs will now be excluded from any Avast scanning

Adding Website/Domain/URL Exception into Avast 2019

On the screenshot above you can see that URLs ‘https://www.gmail.com‘ and ‘http(s)://.gmail.com‘ are excluded. Such exception also applies to all pages on these domains as we have used ‘/*’ in the path.

Add Exception for Specific Avast Antivirus Shield (File System Shield, Mail Shield, or Web Shield)

If you want to add the exception for the specific Avast shield, follow the steps further.

1. Open the Avast user interface and go to ‘Settings‘ » ‘Active Protection‘
2. Select the shield (File System, Mail, or Web) for which you want to add the exception, and click on ‘Customize’ link
3. Find the menu item ‘Exclusions‘ and add the item you want to exclude from scanning by the specific Avast shield. You can also specify when the exclusion applies (for reading, writing, or executing)
4. Please note that global exclusions are always applied although they aren’t listed in the specific shield. Also please note a lot of items are listed there by default

Adding Specific Shield (File System, Mail, or Web) Exception into Avast 2019

On the screenshot above, you can see many items are excluded from the File System Shield scan by default. We haven’t added any of them.

[IMPORTANT] Restart All Avast Shields to Make Exclusion Work

After you successfully add the file or webpage to exclusions you need to actually restart all Avast shields to make it work. Otherwise, Avast will keep detecting and blocking it as a threat.

1. Find Avast icon in the Windows system tray (click on the top arrow)
2. Go to ‘Avast shields control‘ » ‘Disable for 10 minutes‘ » confirm
3. Go again back to ‘Avast shields control‘ » ‘Enable all shields‘

Restarting All Avast Shields From the Windows System Tray

Now Avast should stop detecting the added files/URLs in the exclusions. You can also simply just restart your Windows.

Report a False Positive Detection to Avast

We also strongly suggest reporting the detection you believe is a false positive directly to Avast team. They will look into it and eventually confirm the reported file, software, or website is clean.

This is great but can also get annoying. Avast for mac schedule scan. For example, every time someone walks into your home with a smartphone that is on, you will be notified.

Link to report is included on every in-product pop-up displayed when the harmful webpage or file is blocked. Just click on ‘Report the file as a false positive‘.

Avast Web Shield Has Blocked a Harmful Webpage or File Pop-up

Then you need to fill-in following simple form. In the additional info, you can add a link from VirusTotal scan. Don’t forget to check the option ‘I know what I’m doing‘ and click on ‘Submit‘.

Additional Notes

Although we have used Avast Free Antivirus 2019 screenshots in this article, these steps are also applicable for all Avast Antivirus solutions (i.e. also for Avast Pro Antivirus, Avast Internet Security, or Avast Premier) running the latest version available.

Steps are relevant for all Windows versions – Windows XP, Windows Vista, Windows 7, Windows 8, Windows 8.1 and Windows 10 (including Anniversary Update).

Managing exceptions or turning off Avast protection may leave your computer at risk.

Macs may be a far less tempting target for malware and viruses, but they’re not immune from attack. Even if you don’t care about adware or being used as a means to infect users on other platforms, it’s still possible to fall victim to ransomware, password theft, or stolen iPhone backups.

Accordingly, good antivirus software will protect your Mac on all of these fronts. It’ll catch malware that’s still spreading or in circulation; block ransomware; protect older systems with out-of-date software from security vulnerabilities; prevent your Mac from acting as a carrier for malware aimed at other operating systems; and keep infected files off of any virtual machines you’re running.

Many antivirus suites provide a decent level of protection, but a few rise above all others by providing the very best in performance. Our top contenders dominate by posting perfect (or virtually near perfect) scores from security research labs, passing our own malware detection tests with flying colors, offering well-designed interfaces, and even throwing in extra features like a firewall or password manager.

Updated 08/15/19: Added our review of Avira Free Antivirus, a worthy free option that’s easy to use and effective.

Looking for Windows antivirus recommendations? You can read about the best antivirus suites for PC on our sister site, PCWorld.

Best overall antivirus software

Sophos Home Premium has the most extensive and up-to-date approach to fighting malware at an unbeatable price.

Sophos Home Premium has it all: Effective malware protection, ransomware monitoring, protection against potentially-unwanted-apps, and additional features that often require separately licensed software. Its cloud-based configuration and generous licensing (up to 10 Macs and PCs) also make it easy to shield friends and family from threats, no matter where they live. (Full details available in our review.)

Best free antivirus software

Avast For Mac Shields Blocked Salivary

Though Sophos does offer a good free version of its software, Avast Free Mac Security edges it out as the best free antivirus software for macOS. In security lab tests, Avast detected 99.9 percent of macOS malware, and 100 percent of Windows malware. However, if you want more advanced protection (like ransomware detection), you’ll need to upgrade to paid software.

What to look for in antivirus software

By our reckoning, antivirus software should be able to neutralize a threat before it can begin wreaking havoc. That means preventing the download, installation, or execution of malicious software.

Since you can encounter threats by visiting compromised or malicious websites, receiving virus-laden attachments, or accessing USB drives with malware, good AV software should scan on a continuous basis unless you configure it otherwise. And ideally, files identified as malicious should be quarantined into a special storage area managed by the AV software, with the option to automatically delete files known to be malware or repair normal documents that also carry devious payloads.

Great AV suites also will monitor the filesystem for certain kinds of changes. Ransomware—which is malware that will rapidly encrypt user files like documents and mailboxes and then delete the originals—has become a huge moneymaker on other platforms. Avast mac virus definitions download has failed. As a prime opportunity for attackers, it’s the greatest danger Mac users likely face as a category.

Detecting this pattern and halting it before any files are unavailable should be possible without an anti-malware system knowing the specific innards of a ransomware virus. Sophos, our top pick, includes this feature in the Home Premium version of its 2018 update. Other vendors, like Avast and Trend Micro Antivirus, offer an alternative feature that allows you to whitelist programs allowed to manipulate files in specific directories. So if this particular type of attack becomes rapidly popular, you’ll be protected.

Good antivirus software should also use minimal computational resources. That’s especially the case these days—AV monitoring hasn’t become much more complicated than when it first became available, and faster, multi-core CPUs can easily handle the demands of running AV software in the background without disturbing your active work.

Beyond these primary features, an easy-to-navigate interface and extra features are worth factoring into your decision. Some AV software are full-fledged suites that offer additional options like backup service for essential files, a password manager, parental controls, anti-tracking and privacy modes or options, a more advanced firewall, and the blocking of Potentially Unwanted Applications (PUAs).

How we test

Each software package is evaluated creating a clean installation of macOS Mojave, cloning it for each AV product, and then booting separately into each one to install a different package. This was to ensure that previous app installations didn’t interfere with new ones—sometimes AV software treats other AV software as an infection.

In addition to visiting malicious websites, downloading known malicious software, and even running said malware, we also reference the most recent reports from two labs that regularly cover macOS malware: AV Comparatives and AV-TEST. These laboratories test AV software against sets of known malware as well as products that are grouped as potentially unwanted applications (like adware).

The latter doesn’t damage or expose your computer or its files but may consume power and CPU cycles. Because the testing effectively looks at a combination of virus databases and behavior, they remain good gauges even after many months. When an antivirus software package lacks a rating from a known security research lab, we do more extensive testing with real malware.

Finally, while we gave props for a lot of different features and behaviors, we marked products down if they lacked any or all of the following:

• A nearly perfect score on macOS malware detection
• Ransomware monitoring
• Native browser plug-in or system-level Web proxy
• A high score on Windows malware detection

Privacy concerns

Using an anti-virus product, especially any that includes tools to also improve your online privacy, may lull you into believing you’re safe from personal and private information leaking out. That’s not quite the case. While there’s no reason to panic, you should consider a few reasonable issues.

First, an antivirus product may upload the complete text of files flagged to the cloud, where it can be analyzed by separate tools hosted there. This practice is normal and sensible: Some malware can detect when a running process may examine it, and will then engage in subterfuge. Antivirus software makers also can access their massive databases to examine files with characteristics that trigger their algorithms—certain elements that match known malware. As a result, security researchers discover new viruses, worms, Trojans horses, and the like.

However, helping the greater good means you’ll have to be comfortable with trusting a third-party with your file contents. Where appropriate, we noted privacy policy issues in individual reviews.

Second, this software may also rely partly or entirely on cloud-based checks of URLs, malware, and the like. Accordingly, an AV package might upload every URL you visit, metadata about files, signatures of files, information about your computer’s hardware, a list of running or installed applications, and more. Companies vary on their disclosure of such policies, and may not let you opt out of this kind of sharing. We note issues in each review as available.

Third, anti-virus software makers also get a sense of what behavior is happening on your computer that’s being monitored or blocked, and may use that information for their own purposes. In some cases, you can opt out of this information gathering.
