View Full Version : Must switch server after each update file

When I download updates, it works for the first selected file, starts the next one, but then 'hangs' (i.e. there's no visible activity), before (a little while later) failing with a bad checksum message.

If I switch the download server after each file has downloaded, then the update works fine. However, it's painful - especially if there are 15 or so files to be updated!

Any suggestions? :scratch:

I wonder if the problem lies with the underlying protocol being used (presumably ftp?) and not with Spybot itself, but I'm not sure how I could best test this.

Thanks

Justin

Hello,

Many users have reported that they are not able to download updates. The 'Search for updates' reveals updates, but they cannot be downloaded. Often a 'HTTP Error 403' or 'bad checksum' is displayed. This has a simple reason - millions of people trying to download from the same server, which can't handle such a burden. In combination with the growing size of the detection file this is becoming a serious problem. We are currently considering possibilities to improve the situation. This includes the search for additional servers and ways of more effective compression. At least one server will soon be added, others will follow hopefully.

In order to overcome the problem for now, if you try again, have a second look at the update-menu-bar after searching for new updates. Therefore choose the update site from the navigation bar on the left. Now you'll see the update menu bar. It has a pull-down item to select a mirror. Click the arrow beside it, and select a different location (try the ones locatest nearest to you first), where you'll most probably have better chances to download. For a better understanding we have placed a picture at this link on our website:

In section 4 you'll see how to select a download location nearest to you.

If this sounds too difficult please try to download the updates manually:

Here is the direct download link:
http://www.spybotupdates.com/updates/files/spybotsd_includes.exe
Just download and run that file - it is self-installing.

The information about "bad checksum" is also available in our FAQ:
