It would also be a good thing if the Avast people put some checksum (md5?)
behind the manual update files so that we know that the download is correct.
It won't work if it is incorrect. No way.
Common users don't have a MD5 checksum tool and won't test it.
Ok, that may be a problem.
There are no tools from Windows that do such a check,
only 3rd party (
http://www.md5summer.org/ and alike).
The problem that should be addressed is the full offline update bug imho.
Sure.
And there should be some message on the download page, that there are problems
(and not only in Russia ;-) ).
In my case the files (md5 sum of vpsupd.exe and date)

did not work.
Don't know if that helps.
