Should get to search result #1...
1.
(1.1) R-Clk "{7C260B4B..." in blue in left pane, & select "Delete".
(2) Find Next, & Find Next again. This goes to Search result #3...
3.
(2.1) R-Clk each key in turn that begins "TS..." in the left pane, & select "Delete".
This will eliminate both search result #2 & #3.
Scroll the left pane down. If there is a 3rd "TS..." key there - delete it too.
(3) Find Next to get to search result 4...
4.
(3.1) R-Clk "{7C260B4B..." in blue in left pane, & select "Delete".
(3.2) Find Next may find search result #4.1 - it mentions "LastKey".
If so, let it alone. It is a system key that will self-adjust, as explained before.

6.
(5.1) If there, scroll the left pane down to expose all keys that begin "TS...".
R-Clk each in turn in the left pane (that begins "TS"), & select "Delete".

8.
(6.1) R-Clk "{7C260B4B..." in blue in left pane, & select "Delete".
What is that BHO ({B4F3A835...) under it? Maybe click it, & post a picture. Do not delete.
(7) Find Next likely will not find search result #9.
9.
(7.1) But, if so - R-Clk "{7C260B4B..." in blue in left pane, & select "Delete".
That's it for BHO "{7C260B4B...". Has it disappeared from IE 11? If not, reboot & look again.
