This file is downloaded when you chose to update Spybot-S&D directly during the installation process. I just tested all servers that answer to this HTTP request and they currently all work. So you may just try it again.
If this does not work, you could skip updating Spybot-S&D during the installation and update from within Spybot-S&D directly after the installation finished.
If you still cannot update Spybot-S&D, please report back. Then you may be infected by some Malware that prevents your computer from correctly communicating with our servers. A malware removal expert from this forum will help you in this case.
I apparently downloaded malware but can't load any software (spybot or other) to remove it. Have tried other antivirus/malware programs but none will install. Get '404 - Error opening updallocator.php' on XP.
As for what it is, I haven't had enough time to search on this but it's intercepting all search strings I make and redirecting me to advertising sites. The URL seemingly intercepting my searches is 126.96.36.199
Any work arounds for installing?
btw, I already have Spybot on my computer and am registered but it will not load the program... the hourglass shows up for about a minute then goes away.
