ArticlesKill Macro Viruses


December 1997 / International Bits / Kill Macro Viruses
Stella Kao

As the use of the Internet and e-mail increase, so do virus infection rates. In particular, users are running into an escalating number of so-called macro viruses, bits of malicious code that are hidden in e-mail attachments or in document files. The threat begins the moment you view a Java-enabled Web page.

Steve Chang, CEO of Trend Micro, an antivirus software developer in Taipei, says that more and more corporations are under attack from hostile applets. These programs use Sun Microsystems' Java and Microsoft's ActiveX scripting languages to perform a variety of tasks without the user's knowledge . The rogue ActiveX controls and Java applets, after gaining access to a user's hard disk, execute useless routines, clog RAM, and steal CPU cycles.

Trend Micro's OfficeCall is one of the first antivirus software programs that provides security for both ActiveX and Java components, according to Trend. Using the vendor's patented on-the-fly blocking mechanism, the software can selectively filter Java applets and ActiveX code from unknown FTP- and HTTP-borne viruses right before they can reach the corporate gateway, the company claims.

OfficeCall also incorporates Trend's MacroTrap virus engine. This rule-based scanning technology complements pattern matching with more sophisticated algorithms to examine macro commands embedded in word processing and spreadsheet files and identify malicious code.

The Web-server-based software employs an innovative "push" technology. Instead of requiring each client to log on to the Net and execute time-consuming file downloads, virus pattern updates are pushed from your local Web server to individual clients, which interact with the server via HTTP and CGI. Remote configuration and remote log checking on the Internet also are supported. Users can download a test version of OfficeCall from Trend's site at http://www.antivirus.com .
