Hi

I'm running Windows 7 and could not install a new download earlier today. It was being blocked. I suspected that anti-virus program was the issue. So I completely uninstalled Avast anti-virus to check if it was the cause. It was not.  I still was not able to run the execution file. At that point I thought I maybe infected so I tried to download malwarebytes as a starting point and that failed to run as well. My IE browser does not work at all. But Firefox and Chrome as still working at this point in time. Also, I did sfc/scannow and it detected corrupted files but could not repair them. Any help would be greatly appreciated. Thanks.
