However, going back just because the auto update isn't working would seem to be over kill (unless you have other issues not mentioned) when the purpose of the update to improve avast and fix some bugs, probably more of an issue that the auto update problem.
Can try a manual update if you can then this would seem to be an unnecessary step?
I find it hard to think of a comment in this forum with which I more thoroughly disagree.
The whole reason for the existence of this product is to provide rapid protection to the user community from the latest viruses spreading through the net. If it does not provide that protection it is just so much waste of disk space and system resources and users should be out there looking for a product that will do the job.
This update was advertised to us by Vlk as a minor point upgrade containing very little new functionality.
If you have read through the user responses you will note that most of those for whom automatic update does not work have reported that manual update does not work either. Not exactly a surprise since the automated update is just simply what it says ... an automated manual update.
So this proportion of the users of avast are being left without antivirus updates for a point update that contains very little of use to most of them.
Far better for them to have an old version that does provide virus update protection than a point release update that (for the proportion affected) is totally derelict in its primary purpose.
I think that avast users contributing in this forum are doing a fantastic job in trying to help the affected group but the apparent lack of response and support from the avast team leaves me wondering if my previous faith in them is misplaced.
I suggest to the avast team that, until this issue can be resolved, they should at least provide a link to the 691 version for the affected users.
