In IBM PC clones (DOS), the boot sector is only read during boot up. No
files are read when the disk is inserted unless you execute one from the
disk. Win 95, etc., I can't speak for.

Windows 95 will attempt to autorun a CD, but this can be turned off in the
OS. I am not certain that you can completely disable the CD's being
autoscanned, but the programs, if any, will not actually be run.

Unless the code containing the virus is actually run, there is no
possibility of infection. By inclusion, this includes macro viruses such as
those now found in MS Word and Excel files..unless the infected file is
opened with the proper program, and the macros are run, there is no danger.
