Network access to My Cloud extremely slow...

Just installed a 2TB My Cloud to share files, mostly PDFs, Word docs, etc., nothing like image files, media, etc., over a small office LAN.
Everybody's hooked up to a Netopia 3000 router (supplied by AT&T) & no one is accessing it over wireless.
Copied some files to it & was shocked to find them taking 30 seconds (or more) to open!
I assigned the device a static IP address & added an entry to the PC's hosts file, thinking that may speed it up & the first file I opened took about 4 seconds, but I'm now back to extrememly long (at least in computer time) times to open files.
My Cloud does have latest firmware, too.
What could be causing this & how can I speed it up?

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

What version of Office are you using?

2003, I believe. And I do have - I forget what it's called, but the setting under macros or security set at low, since I'm running AV software on computer.

Will try that tomorrow, when I get back to office, but what is actually going on with the office file validation tool that is causing this behavior?
Davis McCarnOwnerCommented:
It is known to make opening office files across a network painfully slow.  One of my clients had it take XLS files up to 20 minutes to open.

Docs are now opening immediately!
You are a genius, thank you!!
What would possess Microsoft to create such a tool?
Davis McCarnOwnerCommented:
It's supposed to scan every Office thing for macro malware; but, really, really, really hates network shares.
