When there's no user's manual

The stupid anti-virus program that came installed on a computer that I use a lot is a big pain. It permits uploading of photographs to various sites (Flickr, Picasa, e.g.) but, when I go out to the C-prompt in a DOS window and try to upload using FTP commands, I can't upload anything unless I turn off the firewall for the little bit of time it takes. If the firewall isn't temporarily turned off, everything is blocked. And it took me a while to figure this out. Sign me peeved and vexed.
