AutoIt:MalOb-BG [Trj] Blackberry Update

A user received an email from Blackberry about their latest update, with a URL pointing to BB AppWorld. The email is legitimately from BB and the URL really is their site. I assume this is a false positive but don’t trust anything. This is the link that spawned the alert:

http://click.b.blackberry.com/?qs=09a4a920f6596bb5a2ec18d4bc1badea05f289d47249989d7fa7fb1f9946ace2385f1c77ca9332f0
That link translates to:
http://appworld.blackberry.com/webstore/content/22531423/?countrycode=CA&lang=en

I tried it from my own machine just now and the message is no longer seen. Avast did a quick update, or BB changed something on their site???

Anyone else seen or know anything about this one?
