Samsung Galaxy S3 errors

Hi,

I have a Sprint Samsung Galaxy S3 and have been experiencing 2 random pop-ups/dialog boxes.
1. Parsing Error
2. Install Blocked

The only app I downloaded recently was Lookout and that was in attempt to get rid of the problem. After running the scan it told me to delete 2 apps I had on my phone which I did. Since then I am still getting these random pop-ups. I stopped at my local store and they told me the have never seen/nor heard of these errors before.

I don't see an option to upload screenshots, but have them readily available if you need to see them.

Thanks

Greg

The Parsing Error occurred due to corrupted or not fully downloaded application. To resolve this error go to Menu-->Settings-->Applications-->Enable the Unknown sources now try to install your application if problem is same then  first clear the cache of play store. Delete the old application data and redownload the application from play store and install the application.
