Self deleting apps

[vzwbionic]

Please help. Some of the apps on my phone are deleting all by themselves for no reason at all and its getting really old. I've tried moving the apps to an SD card and I've tried keeping them on the phone memory but nothing seems to be helping. One minute the apps are there and the next they are gone. I've notice that most of the apps seem to be games but I've also had to reinstall Instagram, redbox, pandora, vevo, zedge, the draw game everyone seems to be playing now, tweetcaster for twitter, and color note.

Whats the deal?

Thanks
