Thank you for your question.
bmupdate.exe might be ok and might not. As you will note here at Audit My PC:
"...bmupdate.exe - Here is the scoop on Bookmark Updater. The big
question: what is bmupdate.exe and is it spyware, a trojan and if so,
how do I get rid of Bookmark Updater?
bmupdate.exe (Bookmark Updater) - Details
The bmupdate.exe process will check on the internet for available
updates for the drivers of your Visioneer scanner. If updates are
available it is used to manage the download and install of the
updates. If you are not experiencing any problems with your scanner
you can safely terminate this process..."
File bmupdate.exe is related to adware BookmarkExpress.
So, there appear to be two common files with the same name. If you do
not have a Visioneer Scanner, most likely yours is the Adware version.
Spy Any .com says the following:
"...BookmarkExpress is an adware that enables you to view your
bookmarks (such as the last time the site was visited or updated, and
its rating) from anywhere via Internet. It also provides search
function for finding news, products, discussions, Web sites and much
How to Remove BookmarkExpress?
Use the following removal steps to remove this adware:
Open Windows Task Manager (press CTRL+ALT+DEL).
From the process list, find and terminate the following application:
Open the Registry Editor (Click Start > Run, type 'regedit') .
Navigate to and delete the following registry key:
Delete registry values:
Reboot the computer.
Open Windows Explorer, in the address bar, type %WinDir% to enter into
the Windows folder.
Delete the file: bmupdate.ini
Then delete the file bmupdate.exe from System32 directory..."
So this should rid this program from your computer. In worst case, if
you do have a Visoneer scanner, you can visit their website for
updates if you desire.
One last report from Pest Patrol for you:
Adware : Software that brings ads to your computer. Such ads may or
may not be targeted, but are "injected" and/or popup, and are not
displayed within the form of an ad-sponsored application. Some Adware
may hijack the ads of other companies, replacing them with its own.

Date of Origin
You might read their entire report and removal instructions as well.
And last, moving the .exe is a good idea and likely can cause no harm
from there. But there are spyware and adware programs that do recreate
themselves if moved or deleted, so following removal instructions
rather than just moving is always a good idea.
