I upgraded last week from Win ME to XP Home Edition. Everything worked fine for the past 7 days until last night when Windows asked me to install SP2. I installed it with no problem. The security screen starts up automatically and tells you that the anti virus software status is unknown.
I reinstalled Norton SystemWorks without any problems and performed a liveupdate to get the most-up-to-date protection. I then proceeded to perform a full scan to identify any potential viruses. Norton came back with 102 adware/spyware files of which I was able to delete 80 through Norton.
In order to delete the remaining 20 files, Norton suggested that I start msconfig and click on /SAFEBOOT under the BOOT.INI tab. I did this and restarted the computer. At this time I would receive the boot menu from which I can select, Safe Mode, Normal mode and previously known mode. All of these selections would simply perform a restart.
I then selected Advanced Startup by pressing F8 at during the boot cycle. I selected “Do not autostart on failure” and I receive the blue screen IRQL_NOT_LESS_OR_EQUAL. My research tells me that this probably is occurring because of the antivirus software. To be sure I have removed all the PCI cards except the monitor and Ethernet cards to be sure it wasn’t a device driver problem.
After not being successful, I booted the Win XP Home CD trying to perform a reinstall. At this time I receive the blue screen SESSION3_INITALIZATION_FAILED. My research tells me that this is probably occurring because when I originally shutdown, the boot sector was set to /SAFEBOOT.
What can I do next to save this machine? How can I turn the /SAFEBOOT off from a dos prompt?
