I noticed less free space by gigabytes on my boot drive, and took a look why - I noticed a file over 2GB, the scanner.log file for spybot.

Taking a look at it, it's filled with messages from November 2, 'SDFileScanLibrary.DLL' saying a timnstamp with 'Loaded Database'. Googling I found I'm not the only one with this file out of control.
