Does anyone is aware about this HTTP error 400 bad request. I am getting this constantly on my system. Whenever I try to open any website I am getting this error on my screen. I tried to check my internet connection which looks to be working fine. I am getting this error only on some website. Some of them are university websites.

Try to run System Restore. It will restore some old settings which might fix the problem. There are two helpful links below that will help you to deal with the problem.
In the URL try to check for some errors. You get the 400 bad request error mostly because the url typed was wrong or the link that was clicked on goes to a url with some type of mistake in it. This error can also happen if there is some problem with the websites server where you are trying to access. You can try to contact the webmaster and inform them about the error message that you are getting.
