Damage Cleanup Service (DCS) is the built-in Trojan cleaner of Apex One. It performs the following tasks:

• Detect and remove active Trojans
• Repair system files that Trojans modified
• Kill the processes created by Trojans
• Delete files and applications dropped by Trojans
• Reboot clean registries

In addition, RegbootClean64.exe is a file related to Damage Cleanup Service. When the virus was cleaned, Damage Cleanup Service will drop the RegbootClean64.exe file to re-clean the related registries upon reboot.
