More than likely this isn't coming from RCU. More than likely it's coming from a third party that's loading in one of the advertising panes in your browser that you may have navigated through before you went to RCU. To be absolutely sure it's RCU you are getting it from you need to completely reboot your system and then go directly to RCU without going to any other websites and see if you get the same warnings.

I also use Chrome and I'm not getting any any warnings or indications that anything is going on with RCU. Since I work in the IT field for my real world job I have all my systems set to scan constantly because I can't afford to get a virus or spread it to my clients systems, so if there were a coming through the RCU systems I would have gotten a warning by now. However, I will pass your concerns on to our programming staff just in case.
