Hi Blackspear - I am a new NOD user as of yesterday when I installed it using your instructions. Installation went great! I had the opportunity to shut down and boot up twice yesterday and noticed NOD update the definitions and had no problems. This morning when I started my computer and watched it boot up, I saw NOD load first, then Ewido, then ZoneAlarm Security Suite (yes I have the AV turned off along with the AS) and about 4 seconds after everything loaded nicely, I got an error which reads: SVCHOST.EXE -Application error "The instruction at 0x00000000 Referanced Memory at 0X00000000. Click OK to terminate the program Click cancel to de bug the program. OK CANCEL The first time I saw this I mistakenly clicked OK and I had to force a shutdown. I booted up again, and when the error appeared again, I clicked CANCEL. This time every thing was OK after I clicked CANCEL and stays OK while I'm up. But every time I boot up I get the error. I suspected ZA so I told it not to load at startup and re-booted. I still got the error with no ZA. It has to be something that NOD has done since it only happened since installation. Can you please tell me how to correct the situation? Please bare in mind that I am an intermediate user at best so try to simplify your answer.
