DocFusion Workbench blocked by AVG Anti-Virus

Problem Description

Users who have AVG Anti-Virus installed sometimes encounter the error "Cannot Start the Application" when launching DocFusion Workbench. Installations of DocFusion Workbench may also be blocked by AVG and throw the same error. In either scenario, AVG Anti-Virus then quarantines, or removes, DocFusion Workbench from the user's computer even though it is a digitally signed application with a valid certificate.

This error sometimes occurs after an update to Microsoft .NET version 4.8 or an upgrade to AVG Anti-Virus version 2022.3.0.76.

Root Cause

This is not a compatibility issue. It is a known issue with AVG Anti-Virus, free and other editions. 

For security reasons, some applications may be evaluated as a threat by AVG Anti-Virus because of file-system or other behaviours. In DocFusion Workbench's case, there are no specific indications of malicious activity. The only instance in which DocFusion Workbench is blocked by AVG Anti-Virus seems to be the creation of folders on the local disk for application data. While this in an effective preventative measure for AVG Anti-Virus to take, it is a false-positive evaluation of DocFusion Workbench. 

Solution

To resolve this error, and continue installing or using DocFusion Workbench, follow these steps:

1. Disable AVG's Behaviour Shield.
2. If that doesn't work, disable AVG Anti-Virus temporarily.
3. Login to, or install, DocFusion Workbench again.
