Today for the first time I started getting some warnings from ESET that it was blocking addresses with "yontoo" in them. It was only doing this in Firefox and when I visited Google sites like YouTube. I tried to do some research and what I found was that while Yontoo is questionable it's not strictly malware. I tried to go to yontoo.com directly to view their website but it was blocked by ESET (in both Firefox and IE). I'm a little concerned because ESET just started throwing up these warnings today and I've never had the issue before. I haven't made any changes to my computer recently. I do have a Firefox video download plugin installed that is apparently tied to Yontoo; however, I've had it for years and it's a really popular add-on so I don't know why it's started throwing up warnings today. I did not use the downloader today, the warnings just seemed to come up by themselves as soon as I went to YouTube. Did ESET just start blocking Yontoo today? Should I be worried something is not right with my computer?
