Hitman Pro said it was going to delete the t5rc.dll malware on reboot, I waited for the reboot, but instead got the windows blue screen with a fatal system error c000021a. the logon process terminated unexpectedly 0xc0000135. The system shut down.
I could not reboot even to safe mode. I brought the computer in to the repair shop. They cleaned off all the viruses and spyware, and tried to reboot 3 times with a windows xp boot disc. They continued to get the blue screen and could not log into windows. They said that the windows files are corrupted, and the hard drive needs to be wiped clean.
Subsequently, Hitmanpro support finally responded to me and told me to do the following. Then stopped responding to my emails:
"Try to start your computer from the Windows 7 dvd-rom or from Windows Repair and start a Command Prompt.
Use the following commands using the "bootrec.exe" tool to ensure a complete repair of your computer:
Since I was running Windows XP and not Windows 7, I used the Windows XP Installation disk to bring up Windows Repair console.
I did fixmbr and fixboot commands. The "rebuildbcd" command was not an option in the repair console.
Both commands appeared to work, and then I tried to reboot the computer, but got the following error message "The system is not fully installed. Please run setup again."
I ran a chkdsk /r command in case there was a disk problem. It corrected a few minor disk problems.
I tried to reboot into safe mode with networking. It seemed to recognize that I had Windows XP Service pack 3 installed (it was displayed on the corners of the screen), but I got the same error message, "The system is not fully installed. Please run setup again."
The only help I can find to correct this is a Windows XP support is Article ID: 320279 - "The system is not fully installed" error message after you run Sysprep and restart. I do not know if this is applicable, as I did not run sysprep.
Operating System: Windows XP Professional - SP3
Dell Dimension Series, Intel Pentium 4 Processor at 3.2 ghz with HT Technology
One other piece of information: In my original contact with Hitman Pro support, they indicated that perhaps winlogon.exe and explorer.exe were infected with a sophisticated malware, and Hitman Pro tried to restore safe versions of these critical system files. But somehow something went wrong.
This is where I am right now. I would still like to boot up this computer, and any assistance would be greatly appreciated. Thank you.
