Hi Kathie,

There are a few reasons why notifications or pop ups would show on your computer like to notify you to have a possible infection quarantined or removed from your computer's system or at times t could also be due to a suggestion to update your security values
for your Windows Defender. For us to understand your issue better, we would like to confirm a few details to see what troubleshooting can we best apply to your concern:

• Have you performed the troubleshooting steps that was suggested to you by
  Le Boule on this thread last January 2, 2018?
• Are you getting the same issue on other user profiles on your computer?
• Can you provide us a screenshot of the pop-up that you're getting?
• Do you happen to notice when do you get the pop-up on your computer?

In the meantime, aside from the troubleshooting steps that was provided on the previous post, we also suggest to have the troubleshooting steps advised to be started with a
clean boot, to ensure that any possible infection wouldn't be blocking the scans that you'll be performing
on your computer. If in the event that it is still blocked even when on clean boot, we advise that you
create a new user profile and name it as
Test. This is so you'll be able to proceed with the suggested troubleshooting and also isolate the issue if the issue we face is a possible infection or a possible system file corruption, thus leading to your computer's misbehavior.

Please don't hesitate to keep us posted on this and reply to this thread.

 

Windows Defender Security Notification Icon missing?

I noticed that my Windows Defender Security Icon is missing from the system tray on the taskbar for the past few months. Havent installed any other antivirus.

What Ive checked:

• Task manager startup: Windows Defender Security Notification Icon enabled
  
• Taskbar "choose what icons appear": Windows defender security notification icon: enabled
  
• Windows Defender and firewall notifications: all on
  
• Windows Defender and firewall: turned on
  

Things Ive done:

• I have used CMD as administrator and PowerShell to complete SFC/scan and the other repair commands and scans and all of them turned out with 0 issues.
  
• Reset Windows Defender
  

Weird thing I noticed is after Windows updates the icon appears, however when I restart or shutdown and turn on my PC the icon is gone again. Another weird thing that happened is that a few days ago my power shut off and when I turned my PC back on the icon was there, however the next day after turning my PC on it was gone.

I am really confused about why the Icon could be gone just like that?
