    Do I really need an extra anti-virus software for protection, when I have Windows Defender...


    My question is simple, do we really need an extra paid anti-virus software to protect our PC while we have built-in Windows Security. I don't understand one thing, how can a third party software will able to protect windows more efficiently than their own Windows Defender? Are paid anti-viruses more reliable than windows defender or it's just business?

    Windows Defender realtime scanning will not switch on - it detects another anti-virus product.

    Windows Defender realtime scanning will not switch on, and the message suggests there is another anti-virus product present but if there is it does show up in Window 10 UI.

    The long story is that I am troubleshooting a problem with application software. The manufacturer suggest removing Bitdefender because there product is incompatible. I thought I would give this a try, if only to element Bitdefender as a cause.

    Firstly, I upgraded from Bitdefender 2016 to 2017 to see if that made a difference. The application still failed so I decided to try removal.

    • I used the standard uninstall to remove Bitdefender 2017, rebooted but Windows Defender would not start realtime protection because another product was providing realtime protection
    • I download the uninstall application for Bitdefender 2017, ran it then rebooted but Windows Defender would not start realtime protection because another product was providing realtime protection
    • I checked the file system and all Bitdefender files have been deleted.
    • I check the registry and found a couple of references to Bitdefender Wallet, then deleted these.
    • I rebooted but Windows Defender would not start realtime protection because another product was providing realtime protection
    • I reran the uninstall application for Bitdefender 2017 then rebooted but Windows Defender would not start realtime protection because another product was providing realtime protection.
    I can find no traces of Bitdefender so I wonder why Windows Defender detects another anti-virus software. I've check other posts but couldn't find additional steps for uninstalling an anti-virus software. Any suggestions?

    Is Windows Defender the only anti virus program I need?

    Clarification, please.

    Note that this is a Win10-specific thread.

    Are you suggesting that Defender in Win10 (and Win8) does not include an anti-virus component or are you suggesting that Defender in Win10 (and Win8) does not provide sufficient (adequate; comprehensive) protection?
