Spyware-blocking techniques

The Barracuda Web Filter prevents spyware programs from being installed on your users’ systems

and also secures your organization against existing spyware by detecting spyware access to the

Internet and notifying you of infected systems. You can also configure the Barracuda Web Filter to

prompt infected users to run the Barracuda Spyware Removal Tool.

Table 1.1: Spyware Functions

Function Description

Spyware Web site Blocking Barracuda Networks continuously updates a list

containing thousands of known spyware download sites.

The Barracuda Web Filter blocks spyware at the source

by preventing browser and application access to these

locations.

Spyware Download Blocking Spyware is everywhere, even in apparently harmless

downloads from legitimate sites. The Barracuda Web

Filter unpacks and examines every individual file within

17 different types of archives. It also uses techniques to

examine password-protected archives.

Spyware Detection The Barracuda Web Filter not only identifies infected

machines on the network, but also blocks the spyware

communication from those infected systems to the

spyware servers on the Internet.

Spyware Removal The Barracuda Web Filter can be configured to

automatically prompt users to run the Barracuda Spyware

Removal Tool when spyware is detected on their system.

This feature allows users to proactively remove spyware

so they do not have to rely on network administrators to

perform this task.
