Apparent MS update site asking for pasword info

My Norton arrested the following link asking for password info. Anyone know
if this is a real MS link and if so, what is it looking to do and why the
password?

hppt://au download windows update msn download update v5 psfwindowsxp
kb873333 x86 enu 73570b7500b9b0f1b39f5938a9189add1581 df.pst

Many thanks. PW

"Paul W",

No, this does not appear to be the format of one of the download site links
for Windows Update. Although many of the "words" in this string are
trademarks of Microsoft, such as windows and msn and windows xp, this does
not conform to our download site URLs. We also have set up Windows Update
at present NOT to ask for passwords, which is typically a requirement of a
proxy server (firewall). Please let me know if I can be of any further
help.

Sincerely,

Pat Walters [MSFT]
