I have a couple questions:

I have a dial-up ISP. In order to connect to the internet, not only must I dial the number but enter my password. I deliberately set it this way. I do not store passwords on my computer.

If a dialer should get in my system, and one has a time or two, is it possible for it to dial out if I am not connected to my ISP?

If I am connected to the internet, is it possible for it to dial out, and if so how?

If you are not connected to the internet, a dailer cannot dial out; once a connection is established (whether or not you use a password to do so is not important, though you are wise to do so) the dialer will use that connexion to communicate.
Now, aren't you glad you have a firewall?

Ah, good.



Most definitely glad to have a firewall - a Third Party firewall - since Windows firewall doesn't block out-going stuff.

Thanks for the information jgweed

I'm not sure if I got it right but... a dialer is not that malicious program that dials premium numbers making your phone bill huge? So once the dialer gets inside your pc, it can dial while you are not connected to the internet. Infact it usually can't dial while you are using the modem for the internet connection. Someone please correct me if i got it all wrong. Thanks.
