VBscript in Web pages

Are you sure you want it to?

I just had Konqueror spit out a dialog to download (as a file) "index.html".
While I thought it strange, I downloaded it and opened it in KATE.  What 
I saw knocked my socks off.
It was indeed HTML, which included a VBScript.  The VBScript had one 
variable with Textual-Hex (ie, the letters were AE453FC2) and one blank 
variable.  The script then processed the first variable 2-letters at a 
time, converted them to the intended Hex by prepending the characters 
with &h (I'm pulling from memory, so it might have been some other 
characters) and dumping that new Hex-code on to the end of the second 
variable.  When done, the app wrote the new variable to a file, and 
executed it.  Basically that HTML file dumped some malware onto my 
machine and executed it (or would have if I ran VBScript on Winlose), 
all without downloading another file.

Nasty.
