How does one scan an entire network for a computer virus, trojan or worm? I work for a medium size company that has one corporate office and two sattelite offices. The two satellite offices are connected to the corporate office via Sonicwall VPN tunnels. We rely on our business DSL for our VPN connections. Over the past few months, our corporate office DSL connection has become very sporatic (actually drops connections for periods of time throughout the day). We are in the process of ordering a full dedicated point-to-point T1 line for our corporate office. I think this will give us a much more stable connection for our VPN. I am also running Computer Associates Etrust Secure Content Manager for our SPAM and anitvirus solution on server and desktops. Now that you have a little background information regarding my setup, I will give you my question, how does one perform a full "network" scan for any type of infections? I have the antivirus clients running on the desktops and servers (actually scanning files in the background). The reason I ask is becuase, I would like to make sure that the reason our connection drops and slows to a crawl at times is not because of a virus on the network. I have checked the logs on the server form the antivirus scans, and they never show an infection; however, I want to be sure that I am not missing something. I think our ISP probably just over subscribed and our DSL service as gone down hill ever since.

When you get PtP T1's you won't need VPN's. Why add a tunnel with its overhead when you have a dedicated 1.54mbit pipe? It's not going thru the internet. Network scanning from a central server to workstations certainly could add overhead on the dsl pipe. We are configured that we push def files out from a central server but wksts do their own scans. Servers scan incoming traffic but that's it. Never had a problem [knock on wood] Golly gee wilerkers everyone. Learn to Internet Search

Wanderer: Our point-to-point T1 will only be from our ISP to our corporate office. We aren't getting ptp's from our corporate office to our satellite offices, as that would be very expensive as incorporate more sattelite offices.
