Chuzzle.exe trying to execute *.tmp

Lately, Chuzzle from Popcap games has been spamming the Pro Defense with a .tmp file (always a different one each time) typing to execute modifying the registry. It wasn’t doing this for about a week after I installed but just 2 days ago is when it started to. I am not running that program anymore until I know why it is making a .tmp file and that .tmp file trying to modify the registry.
