I accidentally installed MacKeeper/ Conduit several weeks ago in Mavericks. I was able to remove the malware with no troubles. After my upgrade to Yosemite it seems to have come back but there are no files to delete like last time. Help!

Hi all,
I just upgraded from Mavericks to Yosemite, which I think might be the culprit.
I had installed MacKeeper (big oops!) several weeks ago but was able to get rid of it by deleting all conduit/zeobit files with no problems afterward. Now after upgrading to Yosemite it is back. I tried getting rid of it with the same tactics I used before to no avail.
Any help would be greatly appreciated!

Install Mavericks, Lion/Mountain Lion Using Internet Recovery
Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.
Boot to the Internet Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND-OPTION- R keys until a globe appears on the screen. Wait patiently - 15-20 minutes - until the Recovery main menu appears.
Partition and Format the hard drive:
Select Disk Utility from the main menu and click on the Continue button.
After DU loads select your newly installed hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Click on the Partition tab in the DU main window.
Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed. Quit DU and return to the main menu.
Reinstall Lion/Mountain Lion. Mavericks: Select Reinstall Lion/Mountain Lion, Mavericks and click on the Install button. Be sure to select the correct drive to use if you have more than one.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.
This should restore the version of OS X originally pre-installed on the computer.
