Untangle Virus Blocker

Viruses can disrupt business, destroy data, and spread to your customers—a scenario that no business owner ever wants to face. You can now protect your entire network from virus threats with our purpose-built antivirus application. Whether it’s a virus, worms, Trojans or malware, our Virus Blocker keeps emails, webmail, downloads and file transfers safe with the latest advances in antivirus technology, and works within a variety of different protocols.

Your business gets full, comprehensive virus protection, updated regularly, so you’ll always have the most current protection available. Plus, you’ll also get the big picture view of your antivirus environment, including what viruses are being blocked.

Key Features:

• Unlike desktop solutions, Untangle sits at the network gateway so there is only one application to keep up-to-date, and Untangle does that automatically
• Protection on the most common email protocols SMTP, IMAP, and POP
• Protection for webmail and file transfer via HTTP and FTP protocols, an increasingly common route for infection
• Reports and event logs show you what viruses are being blocked on the network

Dual Virus Blocker:

For businesses that want an extra-layer of security, Dual Virus blocker provides a second virus scan using a seperate and distinct scanning engine. This may provide an extra margin of protection during the early stages of a virus outbreak.

Virus Blocker Technical Specifications

Virus Blocker and Dual Virus Blocker protect your network against viruses. As you know, viruses arrive over the network using several techniques, so our Virus Blocker products scan many protocols for viral signatures

• Email: SMTP, POP, IMAP
• Web: HTTP
• File Transfer: FTP

Virus Blocker is based on an open source virus scanner, Clam AntiVirus, while Dual Virus Blocker is based on Global Hauri. Both Virus Blocker products:

• Detect viruses, worms, and trojan horses:
• Scan within archives and compressed files: Zip, RAR, Tar, Gzip, Bzip2, MS OLE2, MS Cabinet Files, MS CHM, and MS SZDD
• Protect against archive bombs, files that are repeatedly compressed. Such files cause other virus scanners or programs to crash or hang by consuming all CPU resources. Intensive resource consumption can occur when other virus scanners scan numerous levels of files within files; however, Untangle Virus Blocker products thwart this technique

What It Does:

Transparently scans HTTP, FTP, SMTP, POP and IMAP traffic for viral signatures

How It Does It:

Virus blocker is based on the ClamAV engine and virus signature database, while Dual Virus Blocker is based on Global Hauri; uses on-the-fly decompression of archive files for scanning and can scan arbitrarily large files

Controls:

• Can be configured to scan incoming and/or outgoing by traffic type
• In addition,
  • HTTP: configurable scanning by file extension or MIME type
  • SMTP: action on detection can be set to remove infection, block or pass message, with or without sender and/or receiver notification
  • POP and IMAP: action on detection can be set to remove infection or pass message (the nature of POP and IMAP protocols prevents messages from being blocked, but they can be scanned and cleansed)
  • FTP and HTTP: “download resume” can be disabled
• Scan trickle rate can be configured to support very large files
