    Can I Delete Old Windows Security Stuff?


    The folder at the end of this path--C:>ProgramData>Microsoft>Microsoft Antimalware>Scans>MetaStore--contains 4 folders named 1, 2, 3, 4. Each of these 4 folders contains a few to a few dozen numbered folders and 1 1-KB file of file type 'IDX File.' Many, maybe most, of the numbered folders are empty. The remainder contain 1 or 2 files of file type 'DAT File.' The latest 'Date modified' on any of these things is 8-23-2015. I'm guessing that's about the time I stopped using Windows Defender/Microsoft Security Essentials and started using other security products.

    At this point this stuff looks like pure garbage. Assuming W10 will let me delete those 4 folders, is it safe to do so? I know there are those who will say not to touch 'system' stuff, but I've done so with no harm. And I have cleaning tools that delete 'system' stuff with no harm done. Also, I'm not sure it's accurate to call Defender/MSE 'system.' If there's anything else in the Antimalware folder that can be deleted, I'll delete that also. So, what say you?

    Thanks.

    Paul, thanks for responding.

    I assume you're talking about the MetaStore folder, or is it Microsoft Antimalware? Thanks.

    I was talking about the Microsoft Antimalware Folder, and I do use MS Defender.

    I don't have that folder either. Why are you in such a hurry to delete it? Seeing that its a Microsoft folder it may cause issues if deleted imo.

    I didn't say I was in a hurry; 6 years is not a "hurry." I don't want garbage on my machine. Anything that hasn't been used in 6 years and was produced by software (Microsoft Antimalware) I no longer use sure sounds like garbage to me.

    I missed the date of these folders in your original post, sounds like they are old Defender/MSE files that are not used in newer operating systems. I would guess you could delete.

    I did mention Defender/MSE in my OP. I don't keep up with that now, but I assume at least one of these is used in W10. For now, I've slightly modified the folder name of Microsoft Antimalware and Microsoft Security Client to make it look like they don't exist. If nothing bad happens, at some point in time I'll delete them.

    I welcome any other thoughts/perspectives.
