http://www.sonymobile.com/gb/tools/update-service/ I suggest you run the update service on your phone and see if that solves the problem. Failing that, try a master reset. As for antivirus software, it's very unlikely that your Java phone will get infected--your camera problem is almost certainly due to a software or hardware issue and not a virus.
Hope this helps.
Thanks Mr Chris Ur plan works!
That's good news!
