This does not sound like normal behaviour. It is normal during a manual or scheduled scan for SAV CE to cache temporary files on the disk, but these should then be cleaned up afterward.
Could you confirm:
- The exact directory you see these temp files appear in?
- What file extension they have, if any?
- If you sort the files by last date modified, when did they last appear? Was it around the time of a scheduled or manual scan?
- What is the exact version of SAV CE that you are running (full numbered version). If you open the local user interface, you should see the version listed there.
