Is It Okay To Manually Delete These Pc Pitstop Files?

I tried PC Matic / Pitstop a while ago but didn't like it. I thought I had uninstalled it, but today noticed that there are still some files on my computer, including a User Account that doesn't display amongst my others when booting the computer. I cannot find the program listed in my Program Files even though the files indicate it is there. With a search, I found the following files listed and wonder if it's okay to manually delete them (since I can't find a way to uninstall them):.

PCPitstop Program Files(x86)
PCPitstop Program Data
PCPitstopDat Program Data
PCPitstop Program Data (Users - AppData, etc.)
PCPitstopSVC.dat User Account Picture (Program Data/Microsoft...)

Thanks.

 

Rather use Revo Uninstaller to remove those remnants.
