So I have various desktops and all have more or less the same issue. In the root of each drive there are randomly named folders generated. Names like:
2b174a7b6cd269132e8dd780
52aebd6aec88ceb00badbc
32601669e81d70e5b9c7c8
ae888118d1365c5a165784ed221b20
So the only common thing seems to be that...
anti-virus
bugs
data recovery
external drives
file deletion
file management
hexadecimal
malware
random folders
rootdirectories
sandbox
system issues
tech support
usb drives
user permissions
windows 10
windows 7
windows 8
windows update
