Windows Defender and Thunderbird

Because Windows Defender bogs down Thunderbird for no good reason, you can to disable real-time protection temporarily to get back to work:

1. Click Windows button and type 'Windows Defender settings'
2. Click on the Defender Security  Center
3. Click on Virus & threat protection
4. Click on Virus & threat protection settings

...correct! they didn't make the organization of Widows Defender intuitively easy did they?!

5. Turn Real-time protection off





You can add your Thunderbird profile directory into the "Add or remove exclusions" list and this should let you turn Real-time protection back on.

Microsoft, fix this!
