Hi,
Release notes for Endpoint Protection and Network Access Control 11

Quarantine scan causes Auto-Protect detections in %temp% folder
Fix ID: 1525749
Symptom: DWHWizard.exe starts the quarantine scan and moves quarantined files in to the %temp% folder for scanning. Auto Protect will occasionally detect these infected files.
Solution: After extracting and re-scanning each quarantine item, the TMP file is deleted unless the state is now REPAIRABLE. Repairable files are used later, either to restore to the original location or to save back to Quarantine (REPAIR_ONLY mode). These files should be clean, so Auto-Protect should not detect anything in them.DWHxxxx.tmp files are scanned and re-detected when new definitions arrive or during a scheduled scan
DWHxxxx.tmp files are scanned and re-detected when new definitions arrive or during a scheduled scan
Symptom: DWHxxxx.tmp files are scanned and re-detected when new definitions arrive or during a scheduled scan.
Solution: After extracting a quarantined item to a temp file, the file is deleted immediately after it is processed
I would suggest to scan your system in safe mode & check.
