Hi Brian,
Thank you for reaching out to Microsoft Community where you can find all the required information about Windows Operating Systems.
When you open any document you get message regarding wow.dll.
To work with the issue, I would suggest you to follow the steps suggested:
Method 1: System File Checker (SFC) Scan
SFC scan will find any missing or incorrect system files and repairs them.
Refer to the site mentioned:
How to use the System File Checker tool to troubleshoot missing or corrupted system files on Windows Vista or on Windows 7

Method 2:
Perform a virus scan using Microsoft Safety Scanner.
Refer to the site:
Microsoft Safety Scanner

Note: Any data files that are infected may only be cleaned by deleting the file entirely, which means there is a potential for data loss.
For any Windows related issuefeel free to contact us.
