Hi Everyone, I'm an ex-member of the "Error Occurred while Scanning operating Memory" club. To be a member you need to be able to reproduce the following on your pc: Error Occurred while scanning operating memory. System memory cannot be scanned (the kernel service is not running or an error occurred while loading nod32m1.vxd) Marcos mentioned in one of the threads this would be resolved in the new version. Well, I'm happy to report that error is gone, but replaced with something even better in v2.5. I'm now forming a new organisation, with a very long and impressive title: The "Unable to Run on Demand Scanner, In Depth Analysis or Scan Local Disks modules" Assoc. Here's a summary: This is a clean installation, WinXP Pro, SP2. NOD32 antivirus system information Virus signature database version: 1.1100 (2005051 Dated: Wednesday, 18 May 2005 Virus signature database build: 5616 Information on other scanner support parts Advanced heuristics module version: 1.013 (20050303) Advanced heuristics module build: 1078 Internet filter version: 1.002 (2004070 Internet filter build: 1013 Archive support module version: 1.030 (20050419) Archive support module build version: 1117 Information about installed components NOD32 For Windows NT/2000/XP/2003 - Base Version: 2.50.16 NOD32 For Windows NT/2000/XP/2003 - Internet support Version: 2.50.16 NOD32 for Windows NT/2000/XP/2003 - Standard component Version: 2.50.16 Operating system information Platform: Windows XP Version: 5.1.2600 Service Pack 2 Version of common control components: 5.82.2900 RAM: 1024 MB Processor: Intel(R) Pentium(R) 4 CPU 3.00GHz (3000 MHz) What actually happens when I try to run any of the scans is the scanning window appears and then vanishes within seconds. My greatest success is with the in-depth analysis scan window which manages to stay on screen long enough for me to see that it reports scanning memory then vanishes the way of the other modules. The old version of NOD was uninstalled by quitting the program, uninstalling via the uninstall utility, deleting the Eset folder and restarting. Downloaded the new version, installed. I have uninstalled and reinstalled 3 times (guess 3 times lucky just doesn't work for me), have also tried downloading v2.5 again in case it was a corruption issue. My next option is to pull my hair out - bald would not be a good look for me! HELP!!!! Calling all resident white knights - Blackspear, Happy Bytes, Marcos to name a few! Thank you to all that aid in my quest to exorcise whatever is haunting this pc!
