I've been getting computers that won't go on the Internet and every time I go to connections and find that there is a proxy setup to go to 127.0.0.1

Something is doing this that a lot of people are hitting.

I've scanned these with several programs and of course there are a number of trojans etc. but not all the same.

If your computer suddenly won't go on the Internet, go to the control panel and click on Internet Options.   Then click on the Connections tab.  Next click on LAN settings.  If you have a check in the box "Use a proxy server for your LAN click on Advanced and see if in the HTTP box you have 127.0.0.1, if you do click cancel and then remove the check from the "Use a proxy server . . ."  click OK and see if you can get on the Internet.
