it might be a virus.

rundll shouldn't be running all the time.

I would suggest running a Scan on you system (after updating the anti-virus) also a goo idea is to try and use a different driver for you modem.

if it's a hardware modem (not PCI or AMR/CNR) try using windows built in "standard modem" driver

if it's a winmodem or PCI modem try obtaining the latest driver for it.
