I have a small LAN set up with a host and guest computer both running XP SP1. To dial out from the host involves the usual window popping up with the ISP and password boxes. However the guest that connects to the internet through the host has all IE boxes greyed out and is able to connect without the usual window appearing. It even dials the internet on its own without a warning. It appears to simply connect to the ISP without going to a site but as it ties the phone line it is EXTREMELY annoying. Please, please someone tell me why it does this and more importantly how to stop it doing it.
It could be a virus or spyware, a full antivirus check is in order also download, install, update and run Spybot from click here to get rid of the dialler and to prevent any more spyware blaster is recommended
Have you tried this with the guest account? In Outlook Express, go to Tools > Options and on the General tab (underneath "If my computer is not connected at this time") select "do not connect". Also untick "Send and receive messages at startup".
After installing, go for the update. Turn the alerts off because they get annoying, you don't really need to know about them as Zone Alarm is preventing access anyway. Any probs with ZA then either have a quick search of PCA's forum or start a new thread - there'll be plenty of help.
