Avast Free Antivirus is Failing to Install

I am trying to install using the most recent download of Avast Free. I have already tried cleaning my file system and registry.

Try OpenDNS or GoogleDNS.

Neither worked.

  • Which version of Avast Free…?
  • OS…? (32/64 Bit…? - which SP/Build…?)
  • Other security related software installed…?
  • Which AV(s) did you use before Avast…?

What ever version is downloaded from the main Avast website.
OS: Win 7 64bit SP1
Malwarebytes
Avira and Malwarebytes

First, be sure to get rid of all remnants of your prior installed AV(s)…!!

Then:

  1. Download Avast Free Antivirus: https://files.avast.com/iavs9x/avast_free_antivirus_setup_offline.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.

PS: Regarding Avast & Malwarebytes, see: https://forums.malwarebytes.com/topic/200324-exclusions-for-avast-users/

Thank you. I will try this now.

OK, you’re welcome.

Looks like that worked. Thanks again!

NP, glad I could help.
