Need help with my Galaxy 10.1 v 3.2 - possibly hacked?

[ssnowden]

A few days ago my Google account was hacked. Well, someone in Sri Lanka was trying to access it, so I assume at least minimum penetration was achieved. Since that date, I have been seeing a notification flash across my tablet's status bar, but nothing shows in the menu. This flash is occasionally accompanied by a "ring" notification sound, though I do not have that tone set for anything (that I can find).

I have tried running Lookout and Avast to see if there is anything obviously wrong, but they keep coming up "No malicious files". I also tried to go through my running apps to see if anything looked out of place, but it all looked normal to me. I'm at a loss as to what to do next. Any suggestions?

Change your password & try airpush detector in the play store. That app will tell you if that notification is coming from an app you installed.

Tapped from a Galaxy Nexus using Xparent ICS

I changed the password as soon as I was notified, and I now have Airpush installed. I'll report back if I still can't figure it out. Thank you!

No good. Whatever is alerting is still there, but I cannot find it.
