The name SDDT stands for Spybot - Search & Destroy - Distributed Testing Client. SDDT was developed to be a small tool that helps improving Spybot - Search & Destroy's updates by letting your computer scan with alpha updates automatically.

Malware is growing to become more and more randomized, and one of the consequences of this is a growing risk of false positives in any anti-malware product. Just testing on more and more laboratory machines never covers the whole live situation out there though, so we thought about a different, more community-like, approach: we've decided to implement a distributed computing concept to back up our internal testing.

You may know existing distributed computing projects: Seti@home for example uses the power of a huge community to look for extra-terrestrial life, Folding@home uses a huge community as well to possibly find more understanding about diseases like cancer.

Spybot-S&D Distributed Testing (SDDT) isn't helping you to make phone calls to Alpha Centauri, nor does it cure diseases, but then, it's also not really taking that much processing time away as if you would use them. It uses the same community power though: the results of the scans of many real live machines, maybe including yours, will help us make safer and even faster updates available!
