I had a very frustrating experience with "expired certificates" and "new programs found" after downloading the new version...it was crippling my computer and no setting changes would work..I looked at my anti-virus program and saw that I had not scanned my computer in 380 days-impossible! I clicked on the date in the tray and saw that Spy-Bot had moved the date back a year-what a pain in the ass this was to troubleshoot-if that's not a bug-I don't know what the definition is! The only change to the computer was the Spy-Bot download!
