I got that message earlier today a few hours ago. I had powered up my steam power several hours earlier and then just before I had made 5 or 6 attempts to upload a fairly small video onto DTube and it just kept crashing giving me an error message. So I closed all browsers and ran a scan on both ASC (Advanced System Care) and SuperAntiSpyware. Both found tons of junk to clean out of the system. Then everything went fine after that.  I hope that helps others who may have the same issue.
