Hi, I just purchased NOD32 but can't get it to run in the background. It worked the first time I installed it, but when I restarted the computer all I got was the splash screen, which displayed for a while and then poped up a dialog box saying that it couldn't install. I can start the program manually and do a disk scan OK, but it says: Error occured while scanning operating memory. System memory cannot be scanned (the kernel service is not running or an error occured while loading nod31m1.vxd) - and it dosn't come up with the screen showing the background processes. I tried re-installing, but still no joy Any ideas about what to do next?
