Windows 10: why would anyone use windows defender? somehow it got triggered and I think it's what...

I have my own paid for anti-virus, anti-malware software. I do not use windows defender. At one point I only had that and an anti-virus but windows defender did not defend.


So now I notice my outlook notebook application (the one you download and use in your computer) will not receive emails. I have this feeling it has to do with windows defender, which I turned off, and should be off still.


Has anyone had this happen? Where it interfered with the operation of another application/software?


thanks,

Gina

Windows Defender Task Schedule/Triggers

[Moved from Windows 10]

Hi everyone. Im having a problem with windows defender task schedule. I have set triggers for the 4 processes under windows defender in task schedule, and then I deleted the triggers. What I noticed the next day is: windows defender performed a scheduled
scan twice. The first time at 8:30 AM. When I checked task schedule after the first scan only the scheduled scan was completed. The other 3 processes which includes (windows defender cache maintenance, windows defender cleanup and windows defender verification)
did not start as yet. Then after about 2 hours I checked windows defender and it says: last scan: Today at 11:30 AM. I was confused because it already performed a scan today. So I went and checked task schedule and saw that all 4 processes were completed at
11:30 AM. So why did It perform the first scan any way? Do you think the trigger I created and then deleted corrupted some of the files there? Or is this behavior normal? Also before I created the triggers for all 4 processes I saw that there were no authors
listed for them. Since I created the triggers I noticed my username and CPU name would show up under author for each process. Now that I deleted all 4 triggers I still see my username and CPU name listed for each process. Is this normal?

You may follow the below steps to check the time set for automatic maintenance.

2. Now if you want the scan to take place at 2:00 Am, set the desired time from the drop down list.

3. Click on Ok.

Now check if the scan takes place at the set time.

You may also follow the below steps to update the defender definitions and check if it helps.
