It looks like your explorer doesn't load. No way you deleted your C:\Windows\system32-folder, otherwise you would not even be able to start up your system.
I guess you are using Taskmanager (CTRL-ALT-DEL) to open Internet explorer (new task > iexplore.exe ) and to browse through your files?
Well, in taskmanager, choose new task and type explorer.exe
Let me know if that loads your explorer. If it doesn't,
Could be that the shell got corrupted, or another malware related file got deleted which was loaded as a debugger under the Image File Execution Option\explorer-key which is no standard anyway.
Using CTRL-ALT-DEL, open taskmanager, type in new task: notepad.exe
Notepad will open.
copy and paste next bold from the quotebox in it:
(don't forget to copy and paste REGEDIT4)
[-HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\explorer.exe]
Save this as fix.reg
Choose to save as *all files and place it on your desktop.
It should look like this:
Doubleclick on it and when it asks you if you want to merge the contents to the registry, click yes/ok.
Reboot and let me know if this solved the problem.
