apps reported as virus
I just downloaded two apps from iTunes, and one of them has been flagged by ClamXav as being a virus:
-Quotes for Cards (for Instagram)
2012-07-24 10:19:21 /Users/{me}/Music/iTunes/Mobile Applications/Downloads/Instaquotes-Quotes Cards For Instagram.tmp/Info.plist: OK
2012-07-24 10:19:22 /Users/{me}/Music/iTunes/Mobile Applications/Downloads/Instaquotes-Quotes Cards For Instagram.tmp/download.app: Worm.VB-900 FOUND
2012-07-24 10:19:24 /Users/{me}/Music/iTunes/Mobile Applications/Instaqoutes 1.0.ipa: Worm.VB-900 FOUND
I let ClamXav move it to the trash, but what else can/should be done? How can I verify whether this is actually a virus? A search for information on the app turned up very little, and nothing at all with reference to a possible virus or malware.
