You have a socks4 firewall running on port 1080? Sounds like Wingate or a similar proxy (this could be bad). Go into task manager, see what programs are running. If you see one you dont recognize (look for the words proxy or wingate especially) and kill them. Do a search and look for the executable. Maybe check add/remove programs. Also, get a virus scanner with an up to date definition and run a full scan.
