Code:

:OTL
:Commands
[purity]
[emptytemp]
[EMPTYFLASH]
[emptyjava]
[CLEARALLRESTOREPOINTS]
[Reboot]

• Then click the Run Fix button at the top
• Let the program run unhindered, reboot the PC when it is done
• Post resulting log.

2. Now, we'll remove all tools, we used during our cleaning process
Clean up with OTL:

• Double-click OTL.exe to start the program.
• Close all other programs apart from OTL as this step will require a reboot
• On the OTL main screen, press the CLEANUP button
• Say Yes to the prompt and then allow the program to reboot your computer.

If you still have any tools or logs leftover on your computer you can go ahead and delete those off of your computer now.
