The couple were previously given a temporary order of protection against Yasin Ajan in July, when Ajan reportedly illegally hopped their fence after being denied entry to their home.
Ajan apparently told police following his arrest that "voices" had instructed him to find Miller.
A Los Angeles Superior Court judge has now ordered Ajan to permanently stay away from Miller and Rogen on threat of prosecution.
Miller sought the new protection order over "fear that he will return", according to court documents obtained by E! News.
"I have difficulty sleeping and look for [Ajan] whenever I come and go from my house," she said in the filing.
