I have a suggestion. If everything else is working fine, try to reinstall Internet Explorer using Add/Remove Programs > Add/Remove Windows Components or your Windows XP disc. If you do not use IE, uninstall and reinstall the browser that you do use. It could be infected/damaged files that are preventing you from connecting to log in sites. Thats just my personal suggestion however.
A tip I use for any unknown software I see on the Internet, always Google the name of the software followed by virus before downloading. Then scan the first 3 pages of results. If a virus or something exists, it will be mention some how on the the first 3 pages of the Google search. This will possibly save you a headache later.
spybot search & destroy virus - this is not a harmful program at all, a legit program backed by many forums.
