I just did a mistake.

I tried to uninstall the program but run aswclear.exe before anything else. So my avast was deleted in safe mode.
I am not using any firewall (I have the nVidia firewall installed but disabled at all times).
I used to have Kaspersky but uninstalled it before installing avast. I have no other security programs.

I downloaded the program again (avast_free_antivirus_setup.exe) from the main site. I noticed that the download status remains stuck when 100% complete and doesn’t let me run it until several minutes have passed (I use Chrome). When completed, I tried to run it and it gave me a setup selfextract error 1006 (000003EE) and tells me to download again…

Heeeelp…
