// FrSIRT Comment - This is a 0day exploit/vulnerability (unpatched)
// If a user clicks anywhere on a specially crafted page, this code will
// automatically create and execute a malicious batch/exe file.
//
// Update (08.05.2005) - The Mozilla Foundation patched (partially) this
// issue on the server side by adding random letters and numbers to the
// install function, which will prevent this exploit from working.
