How to remove adware.qoolaid from the registry?

1. Click Start > Run.
2. Type regedit
   Then click OK.
3. Navigate to the subkey:
   HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
4. In the right panel, delete the value:
   "winsync" = "%System%\[6 RANDOM CHARACTERS].exe"
5. Exit the Registry Editor.

-----------------------------------------------------------------

Now i followed the steps a, b, and c but i don't know which values to delete from the right panel, as i have 17 values in the panel but they are not all .exe files. The only 6 random character.exe is

C:\WINDOWS\system32\APD123.exe

also i have a 7 and 8 random character .exe as follows

C:\WINDOWS\system32\hkcmd.exe

C:\WINDOWS\system32\igfxtray.exe

my question is, which files do i delete, though i think i should only delete

C:\WINDOWS\system32\APD123.exe

   am i right in my conclusion? Thanks for reading my thorough and stupid question. Please respond.
