4. Handle False Positive Detection
In some instances, the detection flagged by your antivirus may be a false positive. If you suspect this to be the case with the Trojan:JS/FakeUpdate.HNAP!MTB detection, there are a few steps you can take to prevent it from reappearing. The first method involves stopping the antivirus from flagging the file. Begin by opening Microsoft Defender and navigate to the Virus and Threat Protection tab. Within this section, locate the Protection History sub-menu, which logs all the antivirus activities and detections.
By reviewing the protection history, you can find the specific detection you believe to be a false positive. Click on this detection to reveal an Action menu. From here, select the Ignore option to instruct Microsoft Defender to disregard this file in future scans. This step effectively tells your antivirus to overlook this file, preventing further false positive alerts. This approach is particularly useful for cache files in web browsers or other applications that may inadvertently trigger the detection system.
5. Ignore False Positive
If you determine that the detection is indeed a false positive, and you have followed the initial steps to handle it, you should proceed to ignore the false positive alerts effectively. In the Protection History of Microsoft Defender, find the specific detection entry and click on it. The detailed view provides options for the detected file. From the Action menu that appears, choose the Ignore option. This step confirms to Microsoft Defender that the file is safe and instructs the antivirus to disregard it in subsequent scans.
Choosing to ignore the detection should only be done if you are certain that the flagged file is not harmful. This approach prevents recurring false positive alerts, allowing your antivirus to focus on genuine threats. For users who often encounter false positives due to the nature of their work or the websites they visit, learning to manage these detections efficiently can save time and reduce unnecessary concerns. Continual observation and periodic reviews of the protection history also help in maintaining a balanced and effective security posture.
6. Delete Falsely Flagged File
Alternatively, if ignoring the false positive detection is not an adequate solution for you, removing the falsely flagged file from your system can be effective. This is particularly useful if the detection happens in the web browser cache, which accumulates various temporary files over time. Browsers have built-in functionalities to clear cache files easily. Removing these files ensures that the antivirus does not flag them in future scans, further enhancing your system’s smooth operation.
While clearing browser cache is a routine maintenance task, it becomes crucial when dealing with false positive detections. Removing unnecessary cache files not only helps in preventing false alarms but also optimizes browser performance. This straightforward approach is convenient and can be done periodically to maintain both security and efficiency.
7. Clear Browser Cache in Google Chrome and Edge
