How to stop spam apps?

I have a Blackberry 9320 Curve and for the past couple of weeks I have been getting spam from a particularly Blackberry OS App
called Srid Games and comment is App For You. I cannot even open the app that is advertising in my messages and have no idea where this is coming from?

There is also no option to block it, all I can do it delete it. I get it several times a day every single day. Help??? I want to stop getting this and am worried it is going to affect my data plan costs on my cell carrier.

Thank you,

like you said you might just have to delete it. You might be able to change the permissions of the app to stop it. What are the permissions?
