As you can find what error I am getting when I try to install AVG. The error says some reading error c:\windows\system32\drivers\etc\hosts. I had gone inside the host folder located in system32 and there are two dll files located. The one is kernel32 and the other one is shell32. Those files looks proper. Again when I tried to run AVG the same error appeared. There is no virus in my system and avg is not working. The installation is also not responding well here. If there any dll file missing error then how does those two files are listed. Are they somehow related to the error.
