It's important to properly configure antivirus scanner running on a machine with Acronis Files Connect so that it won't negatively impact the software's workflows. Otherwise there might be occasional locks on files in AFP-shares, performance slowdowns or even index corruption.

1. First of all, add the installation folder to the exclusion list of your antivirus scanner. By default it's C:\Program Files (x86)\Acronis\Access\Access Connect.
2. If you're using Acronis Content Indexing and indexes are located outside the installation folder, add them to the exclusion list too. The default path for indexes is set at Settings > Search in the admin console (more information here), but there is also an opportunity to set another path in Indexing Options at a volume's Properties (more information here).
3. And also disabling scanning files on read (sometimes referred to as scan on access) will greatly improve performance since the Finder browses will trigger a read request on the file system. Scan on writes/modifications only is the recommended setting.
