Battlelog web plugin and ESN Sonar questions

I haven't played A battlefield game in almost 2 years. I had uninstalled them and origin from my PC as I didn't.play them. I removed punkbuster as it wasn't needed. But just today I was checking my programs and features under control panel and I say Battlelog Web Plugin, and ESN Sonar were there. They had never shown there before. I am wondering as to what could have made them show there. If I should be worried or not. I already uninstalled them, but I'm not to sure what to think. I know they are official things, but why did they just randomly show up there. Should I be worried my PC has something unwanted on it. I ran a AV scan a couple days ago and nothing came up.

If anyone has any answer please let me know.
