Am I being hacked or other?

I am using Windows 8.1. Yesterday I did a full scan and quick tune  up. Today I have over 2000 items in the junk files.I had tried to install an old card game program that worked on Windows XP. A lot of the junk files are error reports . not critical, and Windows updates.thousands,. Should I be worried?  (I tried to copy the list as a back up for me and was unable to do so.)   Thanks…Sandy

Sandy,
We do understand your concern, we suggest you to perform the fix and clean option to remove all the junk files. Plesae do not worry, the files may be a older windows updates. It won't make any cause to your device. Thank you!
