internet says I can't connect to proxy server even though I don't use one

[SuperSniperJimmy]

So today I log on to my PC and find out that chrome or internet explorer say they can't connect to the proxy server. I try to go to change this to find out I'm not using one at all. I try turn it on, using safe mode, resetting the internet settings. I also did a full scan with macafee and nothing came up. I've deleted previous programs and files that I have previously diwnloaded and nothing seems to work. Any ideas on a fix?

Then, clear proxy settings from your browser settings
