1) Can NOD32 run after a safe boot? I know Avast could (and I used to really like those Avast bootscans). Is there any possibility that NOD32 will incorporate a bootscan? Is there any way to load the NOD32 program on a boot CD and let it recognize definition files that might be in a hard drive directory? Could I just copy the latest signature files to a CD along with the program itself? I haven't bought r-w CD's in awhile, but this would be worth it! This would enable me to attempt a scan at a dos prompt. Has anyone tried adding NOD32 to the Ultimate Boot CD? 2) When I was running Avira, I had Bitdefender installed as a 2nd on demand scanner. In previous posts to the other AV software forums, I mentioned how I would close services and shutdown exe files in order to run one AV program or the other. Can the same be done with NOD32? Even though I would shutdown the service of one AV program along with removing it's exe from startup, I noticed upon rebooting, using Process Explorer, that dll files from the program were still loading into Windows Explorer. I'm not sure if that would cause a conflict with NOD32 since the exe files and services wouldn't be running. Does anyone have a 2nd AV program such as Avast, AVG, Bitdefender, or Avira PE Classic installed but not running (just as an added security option)?
