With great sadness I just unnistall Spybot S&D because was making windows 7 ultimate crashing with AppHangB1 in explorer.exe.
This error was happening when im trying to double click any icon in desktop.
I unnistall Spybot S&D and error was gone, this happen to me in 2 differents pc's and in 1 notebook.
All with Windows 7 Ultimate of 32bits.
So i just reporting to you guys, so you can fix this in future versions of Spybot. I hope, that you guys do it soon, because Spybot is my favourite anti-malware software, i always use it to help my current anti-virus software, and they do great team work.
