NIS 2011 - constant disk access (mrclean.db and performance.db)
I booted up my laptop and let it idle for about 45 minutes to allow Norton to do it's stuff. When I came back to it, the drive was still thrashing, but I wanted to use my machine so I tried to load my web browser. That took forever because of all the drive thrashing. I noticed that CCSvcHst.exe was using about 25 to 30 percent of the CPU so I loaded procmon.exe to see what it was doing since the Norton Tasks page said NIS 2011 wasn't doing anything.
It was constant reading and writing to two files: mrclean.db and performance.db. The later more than the former, but when doing both it basically made my system unusable because of all the disk activity. About an hour later it stopped, but what exactly was it doing?
