Welcome to Android Central! It's not clear to me -- did you actually download an apk from that site and install it? Installing apks from random websites is a good way to get malware, since you can't be sure if the site vetted those apks for malware or not. If the apk is for an app that you normally have to pay for, that means it's pirated, and that really increases the risk for malware, since hackers will target popular apps that people will feel so clever about installing for "free."
