sounds like you have picked up a proxy override in your registry.
should be able to find the entry for you, and will delete it upon request.
normally, proxy (ignore the download crap there, they just want to sell you their software, the key types are the important bit) are used to set up internet access with an ISP that requires your web requests go through a specific server, called a proxy, on the way out. That server then does whatever filtering it is programmed to do, fetches the data, filters, and sends back to you. AOL used to love doing this to control their users browsing experience.
Nowadays the function is popular for phishing. Phisher sets up a proxy server that will pretend to be XYZ website. When you are infected by the virus, it makes a proxy entry in your registry to route all traffic through that server. If the server sees a request for the website(s) it is set up to emulate, it sends the false page back to you instead of the real page, you enter your login information, get an error message, and whoever runs that proxy now has your credentials from the site you were trying to access.
I'd try connecting from a different computer and making sure you can still access your accounts on those sites.
