I just recently purchased URL and Anti Virus filtering for UTM-1 450 (R65). I have installed service contract file thru SmartUPdate and verified that Gate in the clusterxl has the license for URL, and anti virus. All updates are successfully except for anti virus. The Smartview Monitor gives Error: Last signature update failed (AV engine failed to install update). I notice in Smartview Tracker shows the anti virus signature was updated on SmartCenter, however the Gateway anti virus signature update failed because "AV Engine failed to install update".
