Uninstall the Avast

Avast Free Antivirus / Premium Security
1

I use ‘avastclear.exe’ to uninstall the avast, but ’ avast antivirus clear uninstall’ is still in my computer. How can I uninstall it or delete it ? THANKS

What do you mean by that exactly? I’m not sure I understand what the exact issue is here.

How to remove avast completely :

  • Remove avast through control panel
  • Run avastclear
  • Remove all leftovers manually (folders/files/registry entries)
4

Now tell us which folders and registry we can delete, because everyone don’t have advanced PC knowledge.

5

Search for avast in the registry and every can be deleted without causing a problem on the system.
What folders/files depend on what is/was installed and where (custom folder for example)

6

Can’t delete those files related with AVAST, because I do not have permission to delete.

7

Avast uninstaller should remove all leftovers, although if i unistall avast, folder in program data still remain.

Yes you can. Take ownership of them first or do it in safe mode or boot from a live linux CD/DVD/USB and delete them.
Avast uninstaller should remove all leftovers
That is what people expect. Unfortunately it doesn't and this goes for many uninstallers from all kind of developers. That is why over time a system starts to work slower and slower. That is why I always have a image from a clean install.

No, it is not difficult at all.
When you click on remove for one of mine tools, really everything will be removed.
If I can do it, then sure all those large companies can do it.

Avast did good job because whole folder from program files are gone, also from user data, only program data folder remain and one “folder” in user registry.
But avast is not able uninstall his own screensaver, so strange…
