Rorschach112 sent me here after trying to help me out in the malware removal forum with an issue that turned into an inability to boot up in Windows XP Professional. Here is my original post in that forum below:
"I started having problems about a week ago with Google searches being redirected, and I came across your site instructions for cleaning and removing malware. I performed the first three tasks below and identified a rootkit during the MBAM phase. Also ran my McAfee Virus full scan without detecting anything. After rebooting and testing my system I still had the same redirect problems. I downloaded GMER and executed it. It detected a suspicious alteration and asked if I wanted to run a full scan. I clicked "No" as per the instructions, and at that point the computer locked up and i was unable to do anything further. I turned the computer off via the power button and tried to reboot, but the computer will now not reboot. I can still get into the SETUP functions at the beginning of the boot process, but I'm not enough of a geek to know what to do when I get there. Obviously, I am unable to get to any log information to send you until I can get back into my computer. Help!
1. TFC completed
2. erunt completed
3. MBAM completed (1 items found: 1 rootkit, which said it would be removed after reboot)
4. GMER downloaded and run to the point of asking if I wanted to run a full scan. When I clicked No, the computer locked up, and now will not boot up."
Rorschach112 suggested that I use my Windows CD to try a repair, and directed me to the link on this site to go through those steps. I did so, and the computer said that the process had completed successfully and the computer would now reboot to complete the setup process. The computer went through the initial BIOS setup page, but never got to the "Windows Starting" screen...just back to a blank screen again. I repeated this process twice, with the same result. He then suggested that I hit F8 during restart, which I did. I was able to get to the screen that allowed me to select Last Known Good Configuration. When I selected that, it brought up another screen that said to select the operating system to start. The only option available was Microsoft Windows XP Professional. I hit Enter, but got only a blank screen once again.
I hope you have some further suggestions I might try!
Thanks!
