On-access scanning for viruses
Back to top

Norman Virus Control for MIMEsweeper detects malware in all messages and files handled by MIMEsweeper. The content is handled according to the configuration set in MIMEsweeper’s policy editor. The NVC scanner engine can also remove viruses and leave the original content intact.
 

Norman SandBox

Norman’s SandBox technology detects new and unknown computer viruses, including trojans and worms. Today, an email worm can infect tens of thousands of workstations in a matter of seconds. The antivirus vendors are expected to find the cure, update the virus definition files, and distribute these to its customers immediately. The need for speed is paramount. Norman’s SandBox is a virtual world where everything is simulated. An emulator provides an environment where possible virus infected executables “run" just as they would do on a real system. When execution stops, the SandBox is analyzed for changes. The SandBox is particularly tuned to find new email-, network- and peer-to-peer worms.

The NVC for MIMEsweeper plug-in utilizes the latest MIMEsweeper APIs offering the best possible antivirus protection with no noticeable reduction in performance of MIMEsweeper itself. Administrators familiar with the MIMEsweeper product family can configure the management and policy settings in the MIMEsweeper management console making it easy to use.
 

Memory-loaded scanning for high throughput

NVC for MIMEsweeper is loaded in memory when MIMEsweeper runs, resulting in very fast scanning and high throughput. On high-traffic networks this makes the product more suitable than a command line scanner.
 

Automatic updates
Back to top

Norman Internet Update (NIU) is an integrated part of NVC and can be configured to regularly check for new and updated files on Norman’s product servers. NIU provides complete updating and upgrading of the application software and virus definition files to ensure that the latest version of the software is always installed.

NIU employs incremental updates of virus definition files to keep the size of the updates as small as possible, thereby reducing download time.
 

About MIMEsweeper
Back to top

MIMEsweeper is a software product from Clearswift that functions as a gateway for SMTP-based Internet email and web communication.

With respect to emails, MIMEsweeper will temporarily hold all emails passing through the gateway whilst it actively searches through each email for unwanted content and remove it from the email, if it is configured to do so. When MIMEsweeper has finished processing, the email is forwarded to the recipient according to the rules defined in MIMEsweeper. Similar techniques are used for web-based threats. Clearswift rely on third-party antivirus vendors such as Norman to provide virus scanning options for their solutions.
