  • Microsoft Security Essentials went out with Windows 7 when it became EOL, but there are a few things you can do to get around this.

Without a doubt, Windows 7 is still one of the most widely used operating systems on the planet. However, even though there are numerous reasons to update Windows 10, customers worldwide are still hesitant.

And we understand their skepticism about Microsoft’s latest offering. Specifically, while Windows 7 offers fewer capabilities, it also has fewer system faults that you can run into in normal use. Unfortunately, there are fewer, but not none.

One of these difficulties related to Microsoft Security Essentials is minor but unpleasant (MSE). Some users were notified of harmful software, but neither a fast nor a complete scan discovered anything. Furthermore, the quarantined file history log is unavailable.

How do I fix Microsoft Security Essentials bugs in Windows 7?

1. Download latest security updates

    1. Go to the Control Panel and click on it.

    3. Select Windows Update from the drop-down menu.
    4. On the left side, click Check for Updates.
    5. Select the updates you want to apply.
    6. Install Updates is the next option.
    7. You may need to restart your computer when the installation is complete to complete the process.

Check for the most recent security updates as your first step. Even though Microsoft has stopped providing upgrades for Windows 7, the system continues to receive security updates.

Furthermore, without those upgrades, you may encounter a variety of problems. Malware security threats aren’t the only ones to be concerned about.

We recommend using a third-party antivirus instead of Microsoft Security Essentials if you don’t use updates. It’s useless without an up-to-date database.

You can discover the problem by downloading and installing free apps or using internet security assessments. Here are a few of the most well-known free security programs:

    1. Go to the Control Panel tab.
    2. Programs that are open.
    3. Uninstall an application is a next option.
    4. Microsoft Security Essentials should be found and uninstalled.
    5. Restart your computer.
      • The most recent version can be found and downloaded here. Pay attention to the architecture of your system.
      • After installing the most recent version of MSE, do a full scan to see whether any earlier issues have resurfaced.

4. Uninstall suspicious programs

Certain programs can be flagged as Possibly Unwanted Software, resulting in the stated issues. If the problem began after a certain program was installed, we recommend uninstalling it.

Furthermore, some registry files can be flagged as probable malware in the Preliminary Scan Results. Therefore, you should add such files to an exclusion list.
