Hey Lately i discovered my computer acts like its behind some firewall/proxy. Well it's not. I read somewhere that it may be because of malware changing your proxy settings but i checked that/run spybot etc and its clean. My ISP doesnt use any proxies either. Windows firewall is turned off. F.e. when i tried to log on yahoo msngr it said it couldn't log me on cause im behind a firewall... Any other ideas ? I run windows xp pro sp2 with all latest patches.
