/verbose
Spybot - Search & Destroy
The command line parameter /verbose is for debugging purposes mostly; during scans, it will show the SBIRuleID of the currently scanned detection pattern in the applications status bar. This might be useful to track down problematic SBI Commands where the scan seems to take just too long.
Updater
When used with the separate updater, this parameter causes it to always show a button that allows you to set up the proxy settings directly in place instead of from the main applications user interface. When run on Windows PE, this button is always shown though and /verbose has no additional effect.
