clients and reset those connections. For example, when spyware has been profiling a user's browsing habits and attempts to send the profile information home, the SonicWALL security appliance identifies that traffic and resets the connection.

The SonicWALL Anti-Spyware Service provides the following protection:

•Blocks spyware delivered through auto-installed ActiveX components, the most common vehicle for distributing malicious spyware programs.

•Scans and logs spyware threats that are transmitted through the network and alerts administrators when new spyware is detected and/or blocked.

•Stops existing spyware programs from communicating in the background with hackers and servers on the Internet, preventing the transfer of confidential information.

•Provides granular control over networked applications by enabling administrators to selectively permit or deny the installation of spyware programs.

Prevents e-mailed spyware threats by scanning and then blocking infected e-mails transmitted either through SMTP, IMAP or Web-based e-mail.
