Why can't I uninstall Avast Free Antivirus? It always says "there is an error" that occurred and doesn't uninstall the product.

Did you exit the application first?

Try with Revo Uninstaller.

In the past when I've had trouble uninstalling programs, sometimes the solution was to repair/reinstall them first.

Try AppRemover:

The portable software program that is compatible with Microsoft operating systems from Windows 2000 to the latest Windows 7 Beta (including 64-bit editions of XP and Vista) can be run right after download. It will scan the computer system for security software programs and display all that have been found in a list. It is possible to remove all or only selected ones from the system.

The reason behind the problem you are facing is that there is an instance of Avast is running in background. So inorder to be able to remove the antivirus software please exit from it (just closing the window may not help).

If this dosen't work try using

REVO UNINSTALLER or IOBIT UNINSTALLER
