Internet Explorer, Firefox and Opera won't load. Chrome will. When Firefox is "loaded" it is in the list of processes on CTRl Alt delete, but nothing is on the screen even after Alt-Tab. I have run chkdsk - no change. What is the cure please?
My first thought would be a malware attack. Using your working browser download Malwarebytes (the free version) - update it and then run in safe mode. Remove anything it finds. Available from click here
