that is probably the virus name from the block message the user received when using the web application. The website was scanned by the McAfee Web Gateway and the Antimalware engine classified the application as malicious based on a heuristic detection.
This doesn't mean that there must be a virus in the web application, but web applications that export data into your a desktop program is normally something that you don't want to allow generally. It's a potential security thread and the ProActive part of the engine blocked the web site.
If the web application is an internal script and trusted it could be scanned without the heuristic detection or completely whitelisted. This has to be done in the Web Gateway configuration.
