Limitations
* Less protection — AVG Anti-Virus Free Edition does not detect potentially unwanted programs.
* No server support — AVG Anti-Virus Free Edition cannot be installed on server operating systems (such as Windows Server 2003), nor can it be used for the scanning of network drives.
* No customization — Scheduling options in the AVG Anti-Virus Free Edition are very limited (only one scheduled update per day, one scheduled scan per day etc.). Also the Resident Shield configuration is limited with no exclusion settings. AVG Anti-Virus Free Edition does not offer advanced testing options, password-protected archives reporting, adjustment of scan process priority and many other features.
* Slower updates — AVG Anti-Virus Free Edition receives updates via a lower priority service. Priority updating via high-speed servers is only available for commercial versions.
* No technical support!..
