I have used AVG server anti-virus for the past year. I finally traced my “nuisance” reboots to this software. Every time the software would update, the server would reboot itself after a few minutes. Needless to say I switched to CA and have had no problems at all. I've had to ditch my last year of service and take the loss. AVG has no information on their website about any such problem. Once, after installing an anti-virus update on this server (Windows server 2003) the entire OS became corrupted and I had to re-install. I have decided that AVG is not the product for me.
