Windows 10 100% hard drive usage in temp directory

I have noticed a huge amount of files being created and removed constantly in folder:

about 30 second after or before - different filenames

What is going on and why is Cis just doing this? :o

OK, looked in task manager - it was full system scan, but it was back-grounded. It is possible to make the scheduler run this scan as normal?

Yes change the scan priority to normal under full scan profile options by checking ‘Run this scan with’ and selection normal from drop-down list. You could also disable heuristic scanning to prevent the temp file creations.

Most likely triggered by ‘Decompress and scan compressed files’ option. :-La
