Have I been infected with a rootkit

So today I recently did a spybot check like I normally do.
and found this

Type: File
Object: eat them.jpgox
Location: D:\
Details: Invisible to Win32

Type: Folder
Object: Boott! s
Location: C:\
Details: Invisible to Win32

Are these rootkits and should I be worried about my computer's safety?

I deleted them with spybot but does anyone know if I should be worried about my private information such as steam account amazon youtube facebook ect ect?

I deleted them but the next scan they still show up help would be appreciated!

Hello chowder908,

Type: File
Object: eat them.jpgox
Location: D:\
Details: Invisible to Win32

Is D:\ an external drive, do you use Play Station?

Type: Folder
Object: Boott! s
Location: C:\
Details: Invisible to Win32

There is an old thread where it is mentioned but I don't know if the user sent the file in.

What is your operating system and how is the computer running in general, any problems?

Best regards.
