Addthis removal help

Hi Everyone.
Unfortunately I tried the addthis plugin, then removed it, but when I run a GTMetrix test, it still shows up as slowing me down.
I have searched my site, and can’t find anything.
I have emailed addthis, which of course didn’t respond.

Any thoughts? Anyone managed to get rid of this horrible plugin?

PS. any other thoughts on my site’s speed, would be greatly appreciated
