The user's Windows 10 computer has run out of free space, and WinDirStat reports 91% of the drive space is taken up by <Unknown>
MalwareBytes ran last night, scanned 455,380 files, with no threats found. This scan took 4 hours and 10 minutes
I installed the latest MalwareBytes update this AM, and I assume that I have another 3 hours for that to finish.
The only major change that the user recalls is that a Cloud 9 connection to what appears to be a virtual desktop was installed around the time they noticed the computer slowing down.
How should I proceed? Thanks.
