    No windows defender antivirus after a windows reinstallation


    Hello everyone,


    I carried out a clean installation on windows 10. When I completed updates, I realized that windows defender had not been updated even though it looked like it had been. Then I searched for windows defender on search box, there was nothing but only windows defender firewall. When I open up windows security, there is no sign of defender antivirus. Is this normal? Before reinstallation, I was using Karspersky antivirus, so I have no idea if anything changed with windows defender antivirus.


    Thank you.

    :)

    Good alternative to Windows Defender on 8.1

    I had to do a format and reinstall on my main rig, and thought I may as well upgrade to 8.1. My only real gripe is my Downloads folder lagging like hell, which I've read is due to Windows Defender. Now I really like MSE/Windows Defender because it's unobtrusive and lets me do what I want to do without pissing me off. Several attempts to try another antivirus program have always resulted in me going back to MSE (either due to viral infection or general annoyance). The lagging, while not an issue per se, is annoying the hell out of me. So I'd like suggestions for a good, free alternative that will be unobtrusive, not try to block everything I want to do (I'm smart enough to know what I'm doing), and not make my PC lag even when running a schedules scan.

    Thanks.
