That's a "feature" that was added to Chrome sometime last year. That message will pop up every time Chrome is opened if you have any addons installed that aren't officially approved, ie hosted in the Chrome App Store. TRH is completely safe though.

Personally I'm still using a version of Chrome from last October. I get a message about it being out of date a couple of hours after I've opened the browser, but it's not nearly as annoying as the one that pops up every time Chrome is opened. I think version 46 was the last one without the "warning feature". As far as I know there's no plans to remove it despite a ton of people complaining about it.
