This User Agent could be something to do with Alta Vista, (like this Novell search gadget: http://www.novell.com/documentation/lg/portal/index.html?page=/documentation/lg/portal/configure/data/adat459.html), or even some relating to The AV Search Database, (http://www.avjobs.com/), an aviation related jobs site.
