Addthis removal help

[ClaireFischer]

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?
