I am currently running the latest NOD32 AV on Win 7 64 bit. Haven't had any problems since updating to the latest verison in July. No new software insatllation but today started noticing that on startup, the ekrn.exe is constantly at 25% cpu and in checking the settings etc, realized that startup scan was running at stuck at 0% wtih "Target: Operating Memory" in the on-demand computer scan settings area. Attempted to Pause or Stop just leave the buttons greyed out. So I went into scheduler to disable start up scan and on reboot, no cpu % spike, but on going into the settings and brining up the comptuer scan settings, the on-demand comptur scanner started again and the same problem recurred with the computer scan being stuck again at "Opearting Memory" No ongoing memory problems, did a memory intergrity check and did not show any problems. settings and turned Hope someone will be able to help me- this has been driving me nuts the whole day! Update: I went into the on-demand scanner settings.. threatsense parameter setup and turned "operating memory" option off and the scan is now proceeding- but I suppose that is not a good idea to leave it off unchecked?
