Resolve Defwatch.exe High CPU Usage Problem

Defwatch.exe is the Definitions Watch Service for Norton Antivirus Corporate Edition. This executable file is run to monitor the virus definition database of Norton Antivirus. If there is any change, the utility will make a note of the change.

Basically, Defwatch.exe keeps a track of the changes in the virus definition database. If the process finds the definitions outdated, the program launches the DefWatch Wizard to update them. When the database is updated, the program also attempts to heal or repair the infected files in quarantine. So, you can say the Defwatch.exe is a Norton Corporate Edition process that informs you to update your virus definitions as soon as they go out of date.
