Virus Scam pop-up ad after paying to remove pop-up ads – Word Shaker HD Lite Review

I paid to remove the pop-up ads, but in the middle of a game, a pop-up ad appeared which said warned my device may be compromised by a virus. [Just click "OK" to download an app to clear the problem]. Creepy! It seemed to be a scam. I will no longer use this app and will find an alternative because I feel this app is no longer safe to use.
