Avast For Mac False Positive Display Settings BETTER
Heuristics Sensitivity: Heuristics enable Antivirus to detect unknown malware by analyzing code for commands that may indicate malicious intent. The default setting is Normal. With higher sensitivity, Antivirus is more likely to detect malware, but also more likely to make false-positive detections that incorrectly identify files as malware. Code emulations unpack and test suspected malware in an emulated environment where the file cannot cause damage to devices. Use code emulation is enabled by default
Avast For Mac False Positive Display Settings
In endpoint protection solutions, a false positive is an entity, such as a file or a process that was detected and identified as malicious even though the entity isn't actually a threat. A false negative is an entity that wasn't detected as a threat, even though it actually is malicious. False positives/negatives can occur with any threat protection solution, including Defender for Endpoint.
Fortunately, steps can be taken to address and reduce these kinds of issues. If you're seeing false positives/negatives occurring with Defender for Endpoint, your security operations can take steps to address them by using the following process:
If you see an alert that arose because something's detected as malicious or suspicious and it shouldn't be, you can suppress the alert for that entity. You can also suppress alerts that aren't necessarily false positives, but are unimportant. We recommend that you also classify alerts.
Managing your alerts and classifying true/false positives helps to train your threat protection solution and can reduce the number of false positives or false negatives over time. Taking these steps also helps reduce noise in your queue so that your security team can focus on higher priority work items.
Alerts can be classified as false positives or true positives in the Microsoft 365 Defender portal. Classifying alerts helps train Defender for Endpoint so that over time, you'll see more true alerts and fewer false alerts.
If you have alerts that are either false positives or that are true positives but for unimportant events, you can suppress those alerts in Microsoft 365 Defender. Suppressing alerts helps reduce noise in your queue.
After you've reviewed your alerts, your next step is to review remediation actions. If any actions were taken as a result of false positives, you can undo most kinds of remediation actions. Specifically, you can:
In general, you shouldn't need to define exclusions for Microsoft Defender Antivirus. Make sure that you define exclusions sparingly, and that you only include the files, folders, processes, and process-opened files that are resulting in false positives. In addition, make sure to review your defined exclusions regularly. We recommend using Microsoft Intune to define or edit your antivirus exclusions; however, you can use other methods, such as Group Policy (see Manage Microsoft Defender for Endpoint.
Defender for Endpoint offers a wide variety of options, including the ability to fine-tune settings for various features and capabilities. If you're getting numerous false positives, make sure to review your organization's threat protection settings. You might need to make some adjustments to:
Check your cloud-delivered protection level for Microsoft Defender Antivirus. By default, cloud-delivered protection is set to Not configured, which corresponds to a normal level of protection for most organizations. If your cloud-delivered protection is set to High, High +, or Zero tolerance, you might experience a higher number of false positives.
Expand Cloud protection, and review your current setting in the Cloud-delivered protection level row. We recommend setting cloud-delivered protection to Not configured, which provides strong protection while reducing the chances of getting false positives.
Depending on the apps your organization is using, you might be getting false positives as a result of your PUA protection settings. If necessary, consider running PUA protection in audit mode for a while, or apply PUA protection to a subset of devices in your organization. PUA protection can be configured for the Microsoft Edge browser and for Microsoft Defender Antivirus.
We recommend using Full automation for automated investigation and remediation. Don't turn these capabilities off because of a false positive. Instead, use "allow" indicators to define exceptions, and keep automated investigation and remediation set to take appropriate actions automatically. Following this guidance helps reduce the number of alerts your security operations team must handle.
Heuristics: heuristics enable Antivirus to detect unknown malware by analyzing code for commands that may indicate malicious intent. The default setting is Normal. With higher sensitivity, Antivirus is more likely to detect malware, but also more likely to make false-positive detections that incorrectly identify files as malware.

Based on my read of the above thread, do I understand correctly that this is a false positive by AVAST? If yes, then is there any action that I need to do to restore full functionality to my Firefox web browsers on my affected laptops?
On January 21, 2022, apps were falsely being detected as malicious by Avast Mobile Security and AVG Antivirus for Android. The issue causing the false positive was resolved on January 22, 2022. We apologize for any inconvenience that may have been caused.
For those who want to use avast virus protection can definitely use it but for this problem I have found a fix, Just by going to the settings and disabling web shield & mail shield fixes the SSL Issue. Here is a screenshot
avast gave me so many false positives i removed it.got tired of going to a site and avast blocking it.would check the site with several online services and the site was clean.installed clam from their website and have sentry monitoring my downloads only.am satisfied with clam but avast needs a lot of improvement before i go with them again.
Once again Avast has clearly demonstrated by this latest controversial issue that they are a windows based Antivirus vendor and that their efforts in developing Mac security products have been plagued by many technical issues. They also have a long history of false positive detections.
It is not necessarily to report/contact osu! as a false positive to your anti-virus product, you only need to permit osu! to run. Hopefully in the future anti-virus programs will whitelist Wine, but this is an upstream issue.
The test measures false positives too. This is where the antivirus marks a file as a potential threat when it is in fact safe. Lots of false positives are annoying for the user as they cause unnecessary alarm and disruption. Avira only registered one false positive, and Avast registered two. Both providers did well here.
A "false positive" or "false alarm" is when antivirus software identifies a non-malicious file as malware. When this happens, it can cause serious problems. For example, if an antivirus program is configured to immediately delete or quarantine infected files, as is common on Microsoft Windows antivirus applications, a false positive in an essential file can render the Windows operating system or some applications unusable.[106] Recovering from such damage to critical software infrastructure incurs technical support costs and businesses can be forced to close whilst remedial action is undertaken.[107][108]
Independent testing on all the major virus scanners consistently shows that none provides 100% virus detection. The best ones provided as high as 99.9% detection for simulated real-world situations, while the lowest provided 91.1% in tests conducted in August 2013. Many virus scanners produce false positive results as well, identifying benign files as malware.[134]
Furthermore, inexperienced users can be lulled into a false sense of security when using the computer, considering their computers to be invulnerable, and may have problems understanding the prompts and decisions that antivirus software presents them with. An incorrect decision may lead to a security breach. If the antivirus software employs heuristic detection, it must be fine-tuned to minimize misidentifying harmless software as malicious (false positive).[151]
Virus removal tools are available to help remove stubborn infections or a certain type of infection. Examples include Windows Malicious Software Removal Tool,[160] Sophos Scan & Clean,[161] and Kaspersky Virus Removal Tool.[162] It is also worth noting that sometimes antivirus software can produce a false-positive result, indicating an infection where there is none.[163]
False positive have occurred again in the new version 3.1.5.2. Ignore this warning if you are affected by this. Please report this false positive to Avast through the Avast App. You can also change to other virus detection software.
