I am have problems with browsers on my PC. I currently have 4 different ones and only 1 works. The remainder produce error messages ie cannot find server or cannot display web page. The only one to work is firefox but IE, Safari , Googlechrome etc all fail to connect. I have run countless scans and removed every possible virus but still nothing. Is there some conifguration i can change to allow all the other browsers to function? I have already done the safemode and virus scan. So any other ideas would be much appreciated.
