Thread:VisualEditor/Feedback/ script ... /script problem when using Bitdefender 2015

Hi, I've noticed that when I edit articles using the VisualEditor, this:  sometimes (maybe always) appears on the first line. If you look through my edit history, only the articles using VisualEditor have this problem, and even then not alll of them (look at the Hydnora Africana edit history. I have Bitdefender Total Security 2015, and I know that this script has something to do with real time browsing protection (I think it scans pages before they load up, but I'm not too sure about this aspect. It would be nice to know why this is happening, and I'm having to check all of my previous edits using VisualEditor, and that would be pretty annoying for every Bitdefender user to have to do.
