First, be sure to get rid of all remnants of your prior installed AV(s)..!!
-> https://www.avast.com/faq.php?article=AVKB11#artTitle
-> https://support.symantec.com/en_US/article.TECH184988.html

Then:
1. Download Avast Free Antivirus: https://files.avast.com/iavs9x/avast_free_antivirus_setup.exe
2. Follow instructions: https://www.avast.com/uninstall-utility (Run this tool for all prior installed Avast versions..!!)
3. Reinstall Avast with the downloaded installer from point 1.
4. Reboot.

Hello Asyn,

Sorry for late reply. I uninstall the previous versions of Norton and Avast and download from the link you provided. But during installation it tell me that there is no enough space to install avast i try to delete some file from c: and did a disk clean up. After that i successfully install the avast and now all are fine.

Thank you very much for your valuable help.
