Deleted Explorer.exe, can't get it back, HELP, please!

I just had something similar happen to me and it turned out that files hadn't been deleted, they had just had their permissions changed so I couldn't see them. Actually, no one could except for TrustedInstaller.
I had to start at drive C and change ownership and permissions on everything.
You can probably boot to Repair Computer and then go to the command prompt.
Change to c:\windows and try start explorer.exe.
If this works you can go from there changing ownership and permissions as needed.
If that's not possible, try control-alt-delete and choose task manager. Then look at processes where you should see explorer running. If you highlight that file, then right click and choose properties, then security, you can see who owns it and what permissions they have.
At least this will let you know it the problem is changed permissions or something else.
It took me 3 days to get this far in fixing my mess so I wouldn't swear by this solution, but I hope it helps.

Ok, I will try to do this, but I'm not sure I entirely understand. I have to go to Repair Computer and then command prompt and entering what you said, that will change my permissions? and as needed? I'm not sure what you mean. Will I need to change the permissions for everything, and how do I do that? How do I specify? and I can't do this on my regular account? Sorry about all the questions. I'm just not very technologically savvy and I'm trying to figure this out.

@Jacee, won't that delete pivotal things in my computer, parts of my registry? And are you sure I can do that with a free version of Malwarebytes?

By the by, I tried going to Avira and getting it to let the explorer.exe back from the quarantine. There were 4 explorer.exe files. I told it to restore them and it said that the objects were already on the computer and asked if I should replace them. I did, and nothing has changed.

There are instances when explorer.exe is infected. Please follow Jacee's instructions.

You are going to be better off backing up your data if you have anything you need to save, and simply reinstalling the OS. It will take less time and headache than fumbling through possible fixes.
