Only one, but it's quite risky... Try to delete it manually from Windows or DOS but if it doesn't work and your HD is NTFS do the following:
Open a window and go "tools", "folder options", "file types". After that click "new" and add "exe", click yes on the message and select "HTML document" from the list.
After that, reboot. Everything will be f*cked up but you will be able to delete the file.
After you delete the file open a window and go "tools", "folder options", "file types". After that click "new" and add "exe", click yes on the message and select "Application" from the list.
Reboot and everything will be OK
