after virus infection explorer.exe does not start automatically (Windows 7)

Hi,

I had a very nasty virus infection, where my computer was locked when started and I was asked to call some numbers in Ghana and Central Africa Republic to get a password to unlock it. 

After running an antivirus from outside windows this message stopped appearing, but explorer.exe is not starting automatically and has to be started manually. 

When infected I changed the information inside Shell for explorer.exe but when I restarted my Laptop its information was changed for something like cmd ....

Now the info inside shell stays explorer.exe, but it is not started automatically when windows is started.

Thank you.
