Virus scan and firewall settings
- It is highly recommended that before any CCH® ProSystem fx® Tax installation is performed, you disable your anti-virus software to avoid potential installation issues.
- Real-time virus scanning must be excluded on all CCH® ProSystem fx® Office directories on both file servers and workstations.
- For CCH® ProSystem fx® Tax, this is the Wfx32 folder. You will need to exclude the drive path and UNC path:
- Network drive: ?:\wfx32
- UNC path: \\Server\share\wfx32
- Server path: Location to the wfx32 folder on the server, Example d:\shares\pfx\wfx32
- Some anti-virus software require that that the individual .exe files in Wfx32 are added to trusted files versus excluding the folder.
- Some anti-virus software also require that you exclude specific file extensions for files that reside in the "?:\Wfx32\Tmp" folder such as *.POB and *.CEL.
- If you receive a lot of errors within the ?:\wfx32\tmp folder you may need to exclude the extension causing the error in your anti-virus program.
- Some anti-virus software need to have the file "tb1040.dat" excluded. This file is located in "C:\Windows\System."
- Some anti-virus software may have Heuristic functions.
- Heuristic antivirus features use Heuristic Analysis, this is an active scanning feature that commonly ignores folder exclusions.
- Some common names of the function: Advanced Threat Detection, Behavioral Analysis, Advanced Threat Defense or System Watch.

Notes
- There have been cases where various anti-virus programs have quarantined files in the Wfx32 folder. When this happens, the program or parts of the program cease to work. If your anti-virus program does quarantine files from Wfx32 you will need to un-quarantine them.
- It is also recommended that you set exclusions for the specific file that it quarantined.
- Depending on what anti-virus program you have, when un-quarantining the file, the anti-virus program may ask you if the file is from a trusted source. If you receive this type of prompt, select the option that marks the file as a trusted file.
- Warning! For data integrity and firm security purposes, you should scan all files on your system on a regular basis. However, these full scans should not be performed when the data is in use, i.e., when users are logged in or during a backup.
- Using file exclusions allows your scanning software to continue to protect your system while ignoring the excluded directories.
- You may want to run a full scan with no exclusions at the start of the day before anyone logs into the CCH® ProSystem fx® products, or perhaps run an automated scan after hours. The key is to close all open CCH® ProSystem fx® files when the scan initiates to run without exclusions.
