Thanks Christian. After reading your post I remembered there is a program called "WhoCrashed" which analyses crash dumps. I managed to locate the cause of the problem: it was a driver installed by an old version of Daemon tools. Uninstalled Daemon tools and problem gone. Thanks again.
Hello, When logged as an administrator, starting an on-demand scanner (command line and GUI) - including rootkits scanning - makes Windows XP SP3 Blue Screen of Death in my system. If I do the scanning - including rootkits - from a non administrator account the scanner finishes without crashing Windows. Can you help? Thanks a lot in advance.
