TECHNICAL DETAILS

SCR#36954 description:

When the content blocking is enabled and the product is configured to 
block certain content types/extensions, the end-user can experience 
problems when accessing certain web sites. The problem is fixed in 
this post-release fix. 

SCR#36763 description:

The product will scan the requests coming from a host listed in the 
Trusted Hosts table, if it is specified there as FQDN (Fully Qualified 
Domain Name) instead of an IP address. This post-release fix solves the
problem and the product will not scan requests coming from trusted hosts
defined the Trusted Hosts table as it is expected.

SCR#36402 description:

The product does not start after the system reboot or manual restart if
there is a large number of sites specified in the Banned Sites table.
The product is attempting to resolve banned sites at start-up and it 
results a timeout on waiting for the HTTPSCAN process to start. In this
post-release fix the default timeout to start HTTPSCAN process has been
increased (1 minute) and it's also possible now to change the timeout 
interval via the StartHttpscanWaitingInterval registry setting. The 
setting should be created under "HKEY_LOCAL_MACHINE\SYSTEM\
CurrentControlSet\Services\F-Secure Anti-Virus for Internet Gateways 
Daemon\Parameters" registry key. For example, the following sets 
StartHttpscanWaitingInterval to 2 mins (120 secs, 78 in hex format):

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\F-Secure Anti-Virus 
for Internet Gateways Daemon\Parameters]
"StartHttpscanWaitingInterval"=dword:00000078
