What Operating system do you have ?

Have you had any other antivirus installed on this system and if so how did you remove it ?

If you used the on-line stub installer (a very small file), it could be down to internet connection issues.

Try using the off-line installation/setup file, see https://forum.avast.com/index.php?topic=228012.0 for download locations, if it is the free version you are looking to install the direct link is below.

By internet connection issues, that could mean problems connecting with the avast installation servers, not necessarily on your system or ISP.

I wouldn't rush to shutdown if the avast installer/installation is really still running.  Potentially it could corrupt your installation.

What avast processes you you see of avast running in the Task Manager ?

If you check the Windows Security Center what AV does it say is running ?
If you hover your mouse over the Avast Tray icon, what is displayed ?
