Question:

What directories need to be excluded from resident virus scanning and regular backups?

Information:

Note: It is essential that the listed working directories are excluded from resident scanning as well as regular backups.  The services are expecting temporary files to be in a certain place and available.  

It may also be necessary to exclude applications such as the product Engine and 7zip from interference.

• While the Trustwave products are designed to warn about the presence of traditional scanners, some new technology scanners may not be detected because they only react to specific activities.

If an outside application is interfering with Marshal temporary files the Marshal services will be affected. 

• Services might halt. 
• Temporary files might not be deleted as expected, resulting in later issues that can be very difficult to trace. 

For background information about this requirement, see Trustwave Knowledgebase article Q21197.

If you are using Bitdefender for Marshal 1.1 see also the information in the related article below.

To learn how to exclude directories from scanning, consult the documentation for your virus scanner.
