    Windows Defender slows down my PC


    Whenever I open any folder with lots of software programs than Windows Defender start taking more thing 50% of CPU usage, continuously. I know that it might be scanning them, but every time?

    It slows down PC too much that the icon of the program takes too much time to load. If it had slowed down it once than I won't bother about it but it happens every time, unless I've disabled real time protection.

    So, is there any way to stop it from using more than half of CPU usage?

    1. You can try something like this to limit its CPU usage:

    Process Lasso - Restrain CPU hogs, automate, and optimize your PC!

    2. Do not use WD and install something lighter like:

    Download Panda Free Antivirus 16.0.1 -

    It would be better if I could do something without installing any other program. :)

    And by the way, about antivirus- I'll buy Quick Heal antivirus but maybe after some months, till then I need to keep this antivirus and btw, I don't like Panda AV. :P

    By the way, thank you for sharing your thought. :)

    If you want some comparative info on AV's, there's a thread over on 7 forums where you can weigh the pros/cons of different AV's.
