What happened to the super file that was attacked after the holidays?

At the end of this long holiday, some of our partners will find something wrong after working all day, how the computer hard drive swells up and slows down, and some of our partners who stay at home may even find something wrong late in the holiday. This time the problem …… is Windows Update again, more specifically, our Windows Security Center (Defender) is not right.

01

After a certain update in the last week of April, in some cases, the number of files in the Windows Security Center’s history file directory (C:ProgramDataMicrosoftWindows DefenderScansHistoryStore) grows from tens to hundreds of files under normal circumstances to thousands or even tens of millions. Such a large number of small files can take up system disk space and read/write resources, rapidly slowing down your computer.

02

To confirm if we have received the impact, first turn on the hidden files visible option in Explorer’s settings. Then go to the directories mentioned above, midway some of them may require the authorization of administrator privileges.

03

If you enter the directory and find that the number of files is obviously problematic, you need to delete them first to restore your computer’s performance and then fix the problem. We can first press Ctrl+A simultaneously to select all, and then press Shift+Del simultaneously to delete these files completely. Then press Win+i at the same time to call out the settings screen, click on “Update and Security” and click on “Check for updates” in the Windows Update screen to download and install the most recent updates.

Theoretically, this problem will be eliminated when you update Windows Security Center to version 1.1.18100.6 with the latest update provided by Microsoft. If you are not sure, you can go to the “Update and Security” page again, click “Windows Security Center” in the list on the left side, and click “Settings” in the bottom left corner of the newly opened page. Then find and click “About” in the newly opened page, and you can see the version of Windows Security Center.

If the engine version shown in the page is 1.1.18100.6 or newer, then you are safe. If the update is still not up to this version, then you will have to keep watching for updates, while keeping an eye on the system disk and the previous directory.
