Hi well it must be something on your PC as I can say 100% this site / organization would never link to casinos. Maybe download Malware Bytes they have a free 30 day trial and it is the best to locate and crush any nasties on your systems.
This it is a superb move to be posting here and on other sites. Keeping yourself active with quit mode is a good way to help stem the urges and by going into the GM program well I have only ever heard good things about this. And by what I have read it is very intense. But good for you on putting yourself forward for this!
