Possible Root Kit?

I installed a program to beta test at the final window of the install a window flashed up and it was so fast all I could see were the word "root kit ".

I downloaded and ran Root Kit Revealer. I know NOTHING about root kits, can someone please decipher this for me and tell me do I have a Root Kit installed on my computer and exactly what is a root kit? I was unable to save the log so used print screen and attached.

And if so, how do I get rid of it? Rook Kit Revealer has no option to remove found entries. The only ones I am concerned about are the 1st 3, I know what the others are.

BTW: upon further comunication the root kit was not installed with their program. But am still concerned that Root Kit Revealer still found things.
Do I or Do I Not have a root kit installed? And if so how do I get rid of it.?
Thanks

 

would be helpful to see the rest of the lines: you can drag the little vertical lines separating the headers to the right to expand that area of the window. Important to see the file names that terminate the path.

Ps: This is a more current article.

PS2:

from PCTechBytes. I'd add fdisk it first.
