Having a read online and it seems like this might be unrelated to PowerShell but potentially some 3rd party dll causing the problem http://www.os2museum.com/wp/anomaly-meaningless-rex-prefix-used/. A few people have found tools like AVG, Raptr have been culprits in the past so maybe check if have any of those installed. I would also search the message and see what other people say.
