Hi, it's a pity you didn't ask here before doing anything. Running CCleaners registry cleaner can and does present risks, especially if you combine it with Avast and Malwarebytes, the latest version of malware bytes enables the full version as a trial then you can revert to the free version, the full version will conflict with Avast, which in-itself conflicts with windows ten.
You really only need windows defender.
Use malwarebytes uninstaller and Avast's uninstaller to be rid of them, if you made a backup of the registry using ccleaner please restore it.
Once done open a cmd prompt as admin, go to search and type:- command prompt right click on the returned command prompt and select "run as administrator" an elevated cmd prompt will open. Copy ALL the cmd below into the cmd prompt window.
echo > 0 & systeminfo | find /V /I "hotfix" | find /V "KB" >> 0 & WMIC /Node:localhost /Namespace:\\root\SecurityCenter2 Path AntiVirusProduct Get displayName /format:list >> 0 & wmic PATH Win32_VideoController GET Description,PNPDeviceID /format:list >> 0 & tasklist /v >> 0 & net start >> 0 & echo >> 0 & notepad 0
