@feeks: Select/Deselect all has been added
@Who Knew: the indication was in the status bar earlier, but without the dialog, many people seem to have missed that
The integrated shredder has, as jonathanbean mentioned, been deactivated and is used only for cleanups currently, simple because there are many better stand-alone shredders out there.
@Matt: "rootkit detection" is often requested, but rootkits are actually also just some kind of malware. Some rootkits are detected, some not. If you know some that are not detected, send some information to our detectives and they'll try to add it

Vista support is in 1.5. Immunization for Firefox will come shortly after 1.5.
@DELTRON: shell integration is actually possible, we use single-file-Spybot-S&D scanners e.g. for test automation. It's just that finding files only wouldn't get rid of the associated registry stuff, though we soon might have something for that ready soon.
@noel-pr7: Opera 9 support should be improved in 1.5 as well, we're using many methods currently, from registry App Paths\Opera.exe settings over AppData\Opera\ profile folders, \Software\Opera Software\, etc. Might just be that some detection methods had problems detecting the Opera version (Opera changed a few file formats, some history file now has four instead of three lines per entry or something).
@anonymous user re Select all on updates: right-click on the list gets you a context menu with those choices, since eternities
tsSecure: the IE plugin has grown and will continue to grow, a popup blocker shouldn't be impossible, but then, IE 7 already has one integrated, and older versions tend to not get enough security updates, so I wouldn't recommend them anyway
@arturo_arraiga: we even added Win95 in the list of supported OS back in
Wanted to answer some more topics, but I'll have to go and make todays regular updates ready now
