If I save an attachment to an external hard drive and open it there to discover it is a virus how will this affect the hard drive of my OS ?

It depends on the virus - but it could affect any files/programs that are opened once the virus is in memory

I'm not qualified to answer...but I'll give you my perspective.

Since...it's a system...the location of the malware file...has nothing to do with how it works, replicates, or impacts the system.

The initial file location has nothing to do...with how a program is installed...the files will go to their assigned specific locations.

I imagine that malware operates on the same principle...it's not just something that has an effect where it is dropped temporarily.

A virus delivered via email...does not remain in that email message. Ditto for those transmitted by floppy disk or any other means.

Each malware file executes according to instructions contained therein...those instructions will not allow it to be contained, as long as the location is part of the system.

Is this a generic question, or is this something that happened to you? If the latter, can you tell us which file type (the attachment) and what virus?

Generic. I am trying to decide if it is safe to open an attachment which is moved to an external hard drive without it infecting my OS.

No, it's not safe to open an attachment you don't trust, regardless of its location.
