Our development team has told us that Avast Anti-Virus for Android recently had a bad virus definition that was causing it to “detect” a virus on SongPop, MoviePop, and a bunch of other games that run on the Adobe Air technology (BitStrips, Slotomania, etc.)
According to Avast, they have released a new virus definition that takes care of the bug.
Please know that this was a false report from Avast that has affected a multitude of apps and games.
Updating to the latest Avast virus will resolve this.
Then please reinstall SongPop again.
