Hi tropicalvic,

Let’s follow these steps which should fix the issue.

Step 1

If you have any third party antivirus software and firewall disable them temporarily and make sure that the Windows Firewall is turned on. Then check if the issue reappears.

Step 2

  1. Open Run, and  type in services.msc then press Enter.
  2. In services window, locate Windows Defender service in the services list.
  3. Verify that the Status is Started. If the Status column is blank,

right click on the service and select Start.

4 If you get error trying to force start the Windows Defender service, try to change the Startup Type to Automatic, and then restart the computer.

Hope the information helps. Please post back and let us know.

Regards

    You don't have to,Microsoft security Essentials does it all as long as you keep ur updates up to date there should no problem it takes about a hour to check ur machine information sent to microsoft to sort out problems and they will send updates back to sort out problems.u should try speech recognition if u have the program for it can be very helpful in a lot of ways but my machine can be very cheeky but they are learning same as us.
