Hello, Sorry for my bad English, I’m from Argentina.
We discuss the problem, I have 2 partitions D: \ and E: , the operating system is installed in D: , and when I try to install Avast Free the installer close alone. Try other free and paid antivirus and also all feel the same, the PC is newly formatted.
What could try to install Avast? Of course, thank you very much.
any popup or message are coming or it is close autometically? 
and after which process??
Sorry, I don’t quite understand, what you want to know…!?

nothing, just closes
Thanks, I believe the post in another section.
What interest me is that I can do to install it.
Where is your c partition as that is normally where avast would install itself.
