Windows 10: Problem with explorer.exe

Hi,

I have a very strange problem which I don't know how to deal with. Every time when I start a Window, I've got a black screen with the cursor and after pressing "Ctrl+Alt+Delete' buttons in Task manager. I have to choose "File - New task" and write explorer.exe to be able to use my windows.
Can someone help me? I'll really appreciate any advice how to solve it.

:)

 

How can I remove this virus remnant?

I was also going to suggest Autoruns.

Check to make sure it isn't attaching itself to explorer. It should be the 3rd thing listed in Autoruns, the listing for the Shell. It should just be Explorer.exe. If it is anything else, that might be your problem.

That seems to be an attempt at Option 2 in the tutorial, which requires you to
a. Boot to a command prompt (Did you?)
b. You then seem to be mixing steps 3,4 and 5, thus your command is incorrect.

I suggest Option 1 is easier.

If you still have problems, please repost listing each specific step and saying which option from the tutorial you are using. Thanks.
