We strongly recommend using AVG Free; this software works well with Dr Dispatch and rarely causes issues.

Other software packages such as Avast, Malwarebytes, Trend Micro, McAfee and Norton can cause performance issues with programs that operate on server--> client systems. 

If you must use one of the above packages, then please remember that you must add firewall exceptions for DRD in each of your security programs for proper functionality in DRD.

To install AVG Free, please follow the directions in this link: http://free.avg.com/us-en/homepage
