OK, I think that I have found the conflict, although it will make me choose and compromise my security options. First, a rundown of the hardware involved. The machine that I am working with is a Sony Vaio laptop, model VGN-SZ330P. The critical thing about this is the built in fingerprint scanner and the disk encryption chip and software associated with this laptop. The software in question is the MenuSW software which runs at startup as menusw.exe. If this software is running, and NOD32 is running, I experience the heavy disk access and slow boot. If I disable either software, the boot times return to normal. There must be some conflict between the two. Unfortunately, it means I either have to disable the encryption software, which I do not want to do, or I move to some other AV program other than NOD, which I also do not want to do. I am sure that this is a rather specific case, but I still hate having to make this choice. Any advice out there?
