I am a registered user running Nod32 Version 2.50.45 with signature 1.1406. I am using Blackspear's advanced settings. I run the on-demand scanner (Run Nod32) from the control center. The scanner first checks memory. I then choose 'Scan Only' from the 'Scanning Targets' Tab. The scanner shows the message 'Page file locked' . It then runs for a couple of seconds and then the scan screen disappears and I am returned to the Control Center menu. The same behavior occurs when I select 'In-depth Analysis'. When I look at the NOD32 Scanner log, the result is scanned 0, infected 0, cleaned 0, status scanning. I have never seen this behavior before and never had any problems with NOD32. I have deleted NOD32 and removed its folder and reinstalled but this behavior persists. Any help is greatly appreciated. Thank you.
