Virus Blocker Technical Specifications
Virus Blocker and Kaspersky Virus Blocker protect your network against viruses. Viruses infect networks in many different ways, so our Virus Blocking applications scan numerous protocols for viral signatures including:
- Email: SMTP, POP, IMAP
- Web: HTTP
- File Transfer: FTP
Virus Blocker is based on an open source virus scanner, ClamAV, while Kaspersky Virus Blocker leverages Kaspersky . Both Applications:
- 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, VistaWiz 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 and Kaspersky Virus Blocker use 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
