Hi, i got a warning pop up when windows defender was updating and installing.

I have attached the log file.

Strange. By some reasons it fails into the untrusted area. Could you check your untrusted setup for F:\444b442e506d62b34cd6915858\ path? And why it's using the F: drive? Is It removable?

There is no F:\444b442e506d62b34cd6915858\ in untrusted applications.
Automatically run applications from removable sources (usb) as untrusted is enabled.
I can find no trace of F:\444b442e506d62b34cd6915858\ at all in F drive. ( i have searched with show hidden files and hide protected system files disabled)
It is a removable drive, 1 tb External usb.
I do not normally have this drive turned on unless i am using it, as i only use it for trusted files e.g camera and home videos.
I should add that i am using Windows 7 Ultimate.

If "run apps from removables as untrusted" is on and F: is removable, all is reasonable. The only unreasonable thing is- why Windows Defender is using removable drives to update?
