Hello,
Do you have selected to save the file on disk? Please don't choose to open the file as a download option because you cannot install it through the Internet.
The error seems to be transient in nature and other people seem to have been able to overcome the error by limiting the system resources used by other processes in the system.
In other words, run as little as possible while running the Spybot-S&D scan.
Some users have reported that they only had problems using the beta version but that the final version would work normally. Have you already tried the final version 1.4? (The reason why you don't see it in the integrated update is because we are still preparing an automatic upgrade process for the new version.) If you like, you can install it manually. Please uninstall the old version of Spybot-S&D before you install the new version:

Please don't forget to manually delete the "Updates" and "Includes" folders in the Spybot S&D program folder. You will find links to several download locations on our website. These mirrors are partners who provide places to host Spybot-S&D for us. You can download from one of them, it's secure: http://www.safer-networking.org/en/mirrors/index.html
Please search for new updates after installing Spybot-S&D 1.4.
Or are you using a computer with hyperthreading technology (Intel with HTT)? Spybot-S&D seems to have problems with this technology but we cannot confirm a general problem with HT technology because the software runs normally on our test systems.
One user has reported that turning off Norton Antivirus solved the problem. We are using Norton Antivirus, too, and haven't experienced any problems.
Best regards
