Virus Protection Viruses, worms, and other "malware" can enter organizations by passing through email servers, or by going directly to users who download emails and files from their browsers. Astaro?s anti-virus can protect against both.
Anti-Virus for Email
Astaro's Virus Protection for Email scans inbound and outbound email messages and email attachments carried over industry-standard email protocols (SMTP and POP3).
Anti-Virus for the Web
Virus Protection for the Web scans emails, email attachments, and downloaded files for users who utilize web email services, and who download files from their browser via industry-standard web protocols (HTTP, FTP).
Astaro's Virus Protection 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.
 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.
The software can open and scan more than 700 formats of archived and compressed files.
Technology Partnership
Astaro?s anti-virus uses the database of 100,000 virus signatures maintained by Kaspersky Labs, a global leader in anti-virus expertise. Kaspersky Labs staff of 250 monitors the Internet for new viruses 24 hours a day from three labs worldwide. With Astaro's Virus Protection subscription services, virus signatures can be updated automatically as often as hourly.
Flexible Management
Administrators tailor virus protection to the needs and preferences of their organization by:
- Selecting which file formats to block in email attachments.
- Selecting text strings to use to identify unwanted messages.
- Specifying that questionable messages should be:
- Dropped
- Rejected and error notification returned to the sender
- Passed through with a warning message
- Quarantined for later evaluation and disposition
Reports and detailed logs help administrators troubleshoot and identify patterns of activity.
Performance and Scalability
Astaro?s anti-virus includes features that provide outstanding performance and scalability:
- Intelligent rules select the fastest detection mechanism or combination of mechanisms for each file type.
- Integrating virus scanning with the firewall and spam protection eliminates delays vectoring files to separate systems.
- The software places no limits on the size of files scanned, the number of files scanned in parallel, or the amount of memory utilized for virus scanning.
