Please clarify your response for me. Am I correct about #1 or #2 when using an AMD 64bit processor with the current version of Avast!?

  1. Avast does not scan for viruses properly AT ALL (meaning Avast will not detect viruses during a boot time scan NOR will it properly detect viruses when doing a scan from within Windows???).

-OR-

  1. Avast DOES properly scan for viruses in Windows, but just does not work at boot time without the boot.ini modification?

In addition:

Q. I assume that the boot.ini file which needs be modified is the one in the root of C:? Here is mine:

[boot loader]
timeout=30
default=multi(0)disk(0)rdisk(0)partition(1)\WINDOWS
[operating systems]
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS=“Microsoft Windows XP Professional” /fastdetect /NoExecute=OptIn

I assume you mean just remove the entirety of “/NoExecute=OptIn” as above while leaving the rest intact?

What function does the “/NoExecute=OptIn” provide? Was this line added my Avast originally?

Thank you.
