kaspersky anti-virus tech, with a clue?

it seems that kaspersky anti-virus is "detecting" our hotspot captive portal
login as a "Trojan-Downloader.Script.Generic".

my googling on this seems to indicate that it isn't finding so much a
signature, but something in the url that is "suspicious".

unfortunately, this is causing some fairly unhappy, panicing calls to our
support people from customers.

can anyone point me at a Kaspersky tech with a clue? maybe we can re-craft
our login url to not offend the Kaspersky suite.

note: this hotspot suite has been in operation for 4+ years, and is based on
the chillispot portal.

note: these reports only started recently, so i suspect something was added to
Kaspersky's virus database recently that kicked this off.
