clean your PC

Legacy is a generic detection name by AdwCleaner for potentially unwanted programs (PUPs) that have not been classified by family yet.
Those in your log come from Internet Explorer. Basically they're not seriously dangerous but it's a good thing you clean them. They can come simply from surfing, accepting cookies etc.
I wouldn't worry too much about this particular issue.
adwcleaner might consider these registry keys dangerous because it may be a false positive.

4me doesn't use Internet Explorer as it has been Disabled...!!!

Don't accept Cookies unless they are from Girl Scouts, as far as Surfing, too far from the Ocean...!!!
