    Windows Defender Potentially Unprotected


    I opened Windows Defender, and it said "Potentially Unprotected" scan hasn't been ran in awhile. but I got it set to automatic scans everyday, I ran a scan and it still says the same thing.

    Hey Jcwisgod,

    Hope all is well, are you running any registry scanning tools seen a few people report this as a potential soultion:

    Why does MSE keep saying potentially unprotected?
    MSE will warn you if a scan has not been done, or if a third-party program has deleted one or more of MSE’s files that MSE uses to determine if a scan has been done. This happens if programs like Piriform “CCleaner” or IoBits “Advanced System Care” have been used. These programs should not be deleting MSE’s files. However, to correct:

    • In CCleaner, in the applications tab, uncheck MS Antimalware
    • In ASC, in more settings, in both Quick Care and Deep Care, find MS Antimalware and uncheck.
    (MSE got rolled in to windows defender in windows 8 but is is worth having a look at if this is causing your problem)
    Cheers,
    Harry

    Nope, well I use CCleaner about once a month to delete old files, cookies, etc, but I don't mess with the registry cleaner part. That could be the problem even though haven't used it since couple weeks ago

    It is possible dependant on your settings

    Do you have any other security software installed on your computer?

    You should run more than more software in the security space doing protection and scanning. could deteriorate the effectiveness of both products at providing protection, that could be your problem. This might cause Instabilities and performance problems.

    Yes, I can vouch for Ccleaner (with CCEnhancer add-on) causing the actual problem. About a month ago, I installed MSE on a 7 machine since I put it for family members to use (they know just enough to browse, that's all.) After seeing how it kept saying it "needed to scan" or similar every day, I knew it had to be Ccleaner, so I unchecked the stuff involving MSE in it. It's been fine ever since.

    Going to uncheck windows defender in CCleaner, even though I never check the logs for windows defender
