xp-prof - pc tries to connect to isp every few minutes.

[alidabiri]

hi folks.
i have a desk top (asus/pent-4-2.66/512-ram/xp-prof) connected via a linksys nic card 10/100 to an ibm thinkpad (pent-m/1.6/768-ram/xp-prof) using a cross over cable. the laptop has a pcmcia nic card (xircom - or something) in addition to wireless lan card and 1394 lan card and another lan card. i had to disable these expcept for the pcmcia nic card which worked witth the old laptop.
the connection between the 2 are working properly. even though there's an exclamation mark on the connection icon in systray.
my question is that, every few minutes, the desk top launches dial-up box to connect to my isp.
can somebody tell me why this is happenning? is there a virus? a spyware that is trying to connect and send collected info?
i have ran several virus/spyware checks. and they all say the machine is clean.
can someone please help?

Yes you have a dialer. Download these 2 things and run them. First off download ewido and run a full system scan.

http://www.ewido.net/en/

After running that download hijackthis from the link below. Extract to desktop or prefered folder. Open it up and choose a system scan and save a logfile. Post the logfile on here and unless your sure of what your doing dont attempt to fix anything for most items are legit.

Try the free version of "Ewido"

Are any of your known programs trying to auto update?

thanks guys (both)
i'll give them a try this evening. i had ewido, but it runs out after 2 weeks and wants to be purchased. i have ssd, ms-anti spy, hjt, ad-aware, and norton. none seems to find anything.

If ewido wont work use this.

It is only the Automatic Guard part of Ewido that is stopped after 14 days, you can still update the signatures and use the manual scanning function for as long as you like, that is free.

Are you using internet connection sharing? If yes, is the modem set to make a connection when needed? It could be the other PC prompting this one to make the connection.
