My client is using Norton 360 version 6.
The appregmonitor.log file is almost 14GB in size. The instructions here do not apply. I cannot get to this option or find any log function that seems to affect this file. I deleted the entire security history and that had no affect on this file and I have not found any other logging function that can be controlled.
There must be some way to control the size of this log file. It is clearly out of hand.
