Virus Control

CProxy Server has the ability to scan incoming files for the presence of viruses using almost any command line Anti-Virus scanner. CProxy Server 3.4 AV is shipped with the F-Prot AV scan engine. 

The Virus Control Menu is spread across two menu tabs. The first tab tells CProxy Server which anti-virus scanner to use and the second file defines the actions that will be performed when a virus is discovered.

Files/Actions Tab
The Files/Actions tab defines which files will be scanned for the presence of viruses and the actions that will be performed by the proxy server when an infected file is found.

CProxy Server's virus scanning applies to files that are accessed through the HTTP and HTTP FTP protocols i.e. all files that are accessed through a web browser. CProxy Server does not scan Real FTP downloads.

Scan indicated file types
For CProxy Server to virus scan a file, the extension must be included in the File Types to Scan list.

  • To add a file type, enter the extension e.g. .vbs into the File type to Scan field and click Add. All files with this new extension will now be scanned.
  • To remove a file type, highlight the extension type and click Delete.
  • Existing entries can be modified by highlighting the extension, clicking Edit, making the necessary modifications and then clicking the Add button.

All Files
If this box is checked, CProxy Server will scan all files that are downloaded and the File Types to Scan field becomes File Types to Exclude. Any file types that are included in this list will not be scanned. Note: Enabling this option will dramatically reduce the performance of the proxy server. This mode is only recommended for advanced users who know which file types to exclude.

No Extension Web (HTTP)
If this box is checked, CProxy will scan all files with that do not have an extension type downloaded via through the HTTP protocol.

No Extension FTP (HTTP FTP)
If this box is checked, CProxy will scan all files with that do not have an extension type downloaded via through the HTTP FTP protocol.

Action when Virus found
This group defines the actions that CProxy will perform when a virus has been detected.

  • Delete File: CProxy Server will delete the file and prevent the user from downloading it.
  • Clean File: CProxy will attempt to disinfect the file. If disinfection is successful, a clean version will be sent to the user or else the file will be deleted.
  • Record Log: An entry will be made in the Virus Log file which can be viewed by clicking the View button. The log can be erased at any time by clicking the Delete button.
  • Email Report: CProxy Server will send an email of the virus report file to the address specified in the Email Address field. For this feature to work, you must provide a valid SMTP (outgoing mail) server, an email address to send the mail to and an address from which the mail will be sent.
  • Raise Alert: A message box will be displayed on the proxy server with a virus warning.

Once you have made any changes to the configuration, click the Apply button followed by OK to exit the menu.
