    Windows Defender is disconnected. Why?

    Hello to all!

    My OS is the Win8.1 PRO (64bits) It came pre-installed on my DELL Latitude laptop.
    When I try to use DEFENDER, I receive a message "Defender is disconnected and is not monitoring your system".
    My AV is the ESET NOD32 AV.
    Even if I temporarily disconnect ESET, and try to use DEFENDER I still receive the above message.
    Whats wrong?

    I appreciate any help given to help me with this annoyance.

    Flores,

    Many AV products disable Windows Defender as part of their installation process as they do not play well together. Personally, I use Malwarebytes Premium which works along with Windows Defender and I've found this to be an effective part of my layered defense program.

    If you want to use Windows Defender I'd suggest trying the Windows Defender Offline which will allow you to boot from a USB key and run an offline scan of your computer. I use it about once a month on all my machines as a A/V double check.

    Hello RetiredGeek,

    Did like very much your suggestion to use "Windows Defender Offline" on a bootable pendrive.
    I will try it.
    Thank you so much.

    ESET & Defender cannot be used together/simultaneously. And Defender will only work if & when ESET is fully & completely removed... not temporarily disconnected.

    One cannot ever have 2 AVs in the same box @ the same time. WD & ESET are 2 of the same thing, basically & cannot play together. WD & Malwarebytes are not 2 of the same thing & can play together.

    I found ESET more trouble than it was worth. I kept running into incompatibilities with other software where I had to put in exclusions in ESET to correct. That said, I never found a compatibility issue with ESET and an AV application. I think ESET makes more sense in a business environment with a controlled set of applications.

    And, @ least, certainly, will be no compatibility issues w/ using Windows Defender
