Old versions of avast! and Windows Vista

We are glad to announce that all avast! antivirus editions, including the free Home Edition, now support the new Windows Vista platform (both 32-bit and 64-bit builds).

However, for avast! to work on Vista, you need to use one of its most recent versions. Minimum version of avast! Home/Professional required is 4.7.892. If you're using a previous version, either invoke program update from the avast! user interface, or download and install the latest version from the official download pages.
