Kaspersky Anti-Virus and small offices

I work at law firm which has a total of 6 offices interconnected by a MPLS network and Riverbed optimization. Most of our servers are hosted out of our main office including our KAV server. All of our MPLS lines have T1's to them, and in some cases is not enough to fit the need.

The other day I along with other collueges were looking at the riverbed's optimization and noticed that KAV traffic was not being compressed... at all. One would figure that it should compress easily. Well we did some digging and found that by default KAV transferred updates in a compressed and encrypted SSL format. This was why it wasn't being compressed. See the following link. So we did our due diligence and set the settings to allow compression. Now we are seeing an amazing 95% compression rate! So the LAN tranferred 549MB, but really has only 25MB transferred over the WAN. 

Today, I found while browsing the KAV admin kit, a "Traffic limiter rule"   This rule allows me to setup KAV to bottleneck itself during the day, and unleash it at night.

So Recommendations if you have a KAV Server running operations over a WAN.

• If you have a Riverbed, disable SSL, and compression.
• Create Traffic Rules to limit bandwith usage during the day.
