    Defender Antivirus Service is using a lot of CPU and slowing my computer down severely. How

    Hi DaveM121,

    Thanks for taking the time to help out.

    I ran the "Defender Offline scan" as you suggested, after doing a disk clean-up.

    Unfortunately the "Defender Antivirus Service is still using a lot of CPU? I think it needs a more technical tool.

    Thanks RedRover1

    Defender AntiVirus

    There are 4 options under Defender. Two refer to AntiVirus; AntiVirus Network Inspection Service & AntiVirus Services. Under Startup Type these two are listed as manual and the Status column said Inspection Service is running. When I clicked on the Start
    button in Properties, I got an immediate message: "Win.. Def.. Anti.. Serv.. on local comp.. started and then stopped. Some services stop automatically if they are not in use by other services or programs."
