I have Symantec antivirus corporate edition, but for some reason I can't enable auto protect. In the config option of the program all the boxes are checked which indicates it is enabled but the icon in the taskbar in the bottom right hand corner of my screen shows an exclamation mark and when I right click to enable auto protect for some reason it wont work. Anyone with any suggestions on this matter it would be greatly appreciated.
Is rtvscan.exe service started? Restart the service ( Symantec Antivirus).
Ensure the tampre protection is enabeled so that the threat which is trying to stop the service can be resisisted by this tamper protection service.
