I am running ESS 4.2 on Windows 7 64Bit. I had it setup to run a weekly in depth scan at 03:00am and with the option Wait until next scheduled time selected. This was working fine for a few weeks but now I have a problem. For some unknown reason, one day it started doing a scan at 10:00am, I stopped the scan but this left the ekern.exe process using 50+% of my CPU time. The only way to resolve this is to restart the PC. I removed the scheduled scan completley but it is still starting scans at random times and stopping them leaves CPU at 50+ % I have now uninstalled and reinstalled ESS and didn't set up any scheduled scans after reinstall but it still starts an in depth scan at random times. Any idea how I can stop this as having to restart the PC to stop high CPU usage is getting a real pain. ??
