Virus Protection for the Web

Web downloads and web email
Astaro’s Virus Protection for the Web detects and blocks viruses in files downloaded from the web. It scans all HTTP traffic and FTP downloads initiated from a browser.

Astaro’s Virus Protection for the Web also scans email messages and attachments from web-based email services such as MSN Hotmail, Yahoo! Mail, and Google Gmail. Because these emails don’t go through the corporate email server, they are never scanned by conventional anti-virus packages.

As more computer users utilize web-based email services in addition to corporate email accounts, scanning web traffic becomes critical to keeping viruses from infecting corporate networks.

Dual Virus Scanning Engines

Astaro provides an extra margin of safety by including two virus scanning engines in sequence. Virus detection technology and signature databases from the ClamAV Open Source project and from anti-virus industry leader Kaspersky Lab provide a double layer of protection.

Signature updates from ClamAV’s extensive user community, and from Kaspersky Lab’s renowned international antivirus research team, ensure that new malware threats are identified and blocked as soon as they appear.

High Accuracy

Astaro’s anti-virus utilizes three independent detection methods to catch the widest possible range of viruses:
Virus signatures: Email messages and attachments and web traffic are compared with known patterns contained in an extensive virus database.
Heuristics: Sophisticated rules detect patterns and behavior that resemble known classes of viruses.
Emulation: Suspicious code is executed in a protected environment, for example by unpacking archived files and by running scripts and macros.
There are no limits on the size of files scanned, the number of files scanned in parallel, or the amount of memory utilized for virus scanning.

Flexible Management

With Astaro’s Virus Protection for the Web, virus signatures can be updated automatically as often as hourly.

Administrators can:

• Select which file formats to block in
  email attachments.
• Select text strings to use to identify
  unwanted messages.
• Specify that questionable messages
  should be quarantined for later
  evaluation or dropped.

Reports and detailed logs help administrators troubleshoot and identify patterns of activity.

Astaro’s Virus Protection for the Web complements desktop anti-virus packages by providing a single point of control where newly-discovered viruses can be blocked quickly, before they infect the internal network.

Complete Coverage

Astaro’s Virus Protection for Email can open and scan more than 700 formats of archived and compressed files. Hackers and virus writers can not use obscure formats or complex archiving programs to sneak viruses into internal networks.
