@Spectacle, JFYI,

Sometimes, a “bad download” can make you waste time. For example, downloading Avast’s setup.exe and running it, for you it may seem that everything is fine, but the installation might fail.

Normally, the setup.exe will refuse to run at all if it is not correctly downloaded, but there is a little chance that it still may seem as ok, while in fact it isn’t.

Downloading with a dial up tends to be more “problematic” when it is in a dozens MB size magnitude (or more).

So, using a download manager and inserting the correct checksum helps to successfully download the correct file, and also to be sure it was not tampered with.

Filehippo.com includes MD5 checksums. Although the beta releases are not part of their downloads, they do have all the final stable free releases of Avast (with the respective MD5).

You may want to keep this in mind for future downloads.

(BTW, I still don’t know why Avast don’t use checksums in the original official downloads, including the betas. Or maybe I missed them?)
