GFI releases freeware antivirus version of GFI DownloadSecurity for ISA Server

September 22, 2003 - 12:00

In line with its efforts to promote network security, GFI today released a freeware version of GFI DownloadSecurity for ISA Server 6, its content security product that handles the security risk of file downloads without resorting to blocking them all at firewall level. The freeware version scans HTTP and FTP downloads at the network perimeter using a single antivirus engine, and can be used as additional protection by companies who do not yet perform virus scanning at firewall level.

"Virus scanning of user downloads at firewall level is essential. Although infection by email is much more prevalent, infection by a file that a user has downloaded from a website is just as dangerous and damaging. Most organizations do not protect themselves against this threat. The freeware version of GFI DownloadSecurity allows companies with little or no budget for this type of security to at least install single antivirus engine scanning, thereby benefiting from some protection against infected or malicious downloads," said Nick Galea, GFI CEO.

"Of course, for better security, companies should also scan downloads for unknown Trojans, since Trojans are well suited for distribution by web,” Mr. Galea explained. “The full version of GFI DownloadSecurity offers this facility through its Trojan & Executable Scanner, and the trial version enables users to experience the benefits of this additional layer of defense.”

The recent ZeroPopUp Trojan proved how easily a Trojan can be distributed via the Web. The Trojan was advertised in a spam broadcast that enticed users to download it, describing it as a free product that would block pop-up ads. Once installed, the Trojan sent a mail to everybody in the infected user's address book promoting the ZeroPopUp URL and software, thereby using social engineering to encourage other users to download it too. While this Trojan was simply used to promote software, the same strategy could easily have been used to cause damage to the downloader's network. Further information about Trojans, how they work and the need for special Trojan detection technology is available at

About GFI DownloadSecurity 6 for ISA Server (commercial version)
GFI DownloadSecurity for ISA Server enables administrators to assert control over what files users download from HTTP and FTP sites, and content checks all downloads for malicious content and viruses. GFI DownloadSecurity includes multi antivirus engines, to guarantee higher detection rate and faster response to new viruses; the ability to quarantine downloads based on file type and user; a Trojan & Executable Scanner, to detect malicious executables; network-wide blocking of Java applets and ActiveX controls; seamless integration with Microsoft ISA Server; and more.

Users do not notice GFI DownloadSecurity until they download a file: Then GFI DownloadSecurity displays a download progress dialog box and the download proceeds. Once the download is complete, GFI DownloadSecurity scans the file for viruses. If the file has no viruses and does not trigger a rule set by the security administrator, the user receives it immediately. If the file triggers a rule, it is put into quarantine for administrator approval. Once approved, the file is sent to the user as an email attachment or link. If the file is rejected, the user is notified. More product information and the freeware version can be found at
