Redirecting addon that I can't detect or figure out how to uninstall
I'm sorry if this seems like a total newbie question but I can't figure out if this is a Windows 10 thing or something that's gotten under my radar and is a bit more sinister - everytime I start up a browser, Firefox or Chrome, I get this page Dropbox - Screenshot 2015-12-23 19.44.32.png and I don't know why and it's really annoying. I installed avast to do a virus scan (it found nothing and also broke my internet so I have since had to uninstall it) and I can't seem to find anything out of the ordinary in my add-ons/extensions etc (not to mention I have not installed anything like that for Chrome since I don't use it).
Anyone know what I can do? I also looked at my installed programs and couldn't find anything I didn't recognise.
