Windows 10: Uninstalled Avast, but it still shuts down Windows Defender

I've been experimenting with various AV programs. I had installed Avast (free) as a trial, then decided to uninstall it. I used iobit uninstaller. Then I wanted to make sure WD was back in operation but saw the message that Avast was still in control. What can I do to get WD back into normal operation? Does it require going into the registry, which I'd like to avoid? There must be a vestige of Avast left over.

I use Revo uninstaller on my other laptop. Revo vs iobit...are both equally good or is one better, in your opinion?
BTW, I think Avast is a good program; I'm just experimenting.

Uninstalled Avast to use Windows Defender, tells me to uninstall Avast...

So I had Avast on my computer as my anti-virus program, and was really annoyed at the pop-ups I'd constantly get, so I uninstalled it, and decided to use Windows Defender.

I tried to turn on real time protection, but it tells me uninstall Avast first....I not only uninstalled avast, but I deleted it's remnants from where it was kept in my hard drive.

Any suggestions on what I should do?

Thanks!

How do I remove Avast so I can use Windows Defender?

These are the instructions provided by avast.

• Avast 2016: Uninstallation via the Windows Control Panel <-
  scroll down if you need to use the Avast Uninstall Utility (avastclear.exe)
• Avast 2016: Using the Uninstall Utility
  
• Uninstall avast Antivirus using avast! uninstall utility (avastclear.exe) <-
  recommended to run in safe mode

After removal of the third party anti-virus, Windows 8/10 Defender needs to be
activated if you choose to use it. When uninstalling the third-party anti-virus Defender should automatically turn on. In some cases you may receive a

message indicating your system has no protection...click here to turn on Windows Defender. If not, and Defender remains disabled, you will need to manually turn it on.

Protecting the computer (windows defender,avast, etc)?

Agreed with Firefox w/ Adblock Plus and NoScript. I suggest Antivir. Very trustworthy Antivirus and is less resource hogging the avast. Takes up about 40mb with guard enabled and 30mb with guard disabled.
