When I initiate Safe Mode per instructions and select Safe Mode with Networking then Windows XP I get message that Windows has been shut down due to a problem detected.
Tech Info: STOP:0x0000007B (0xF89D5528, 0xC0000034,0x00000000,0x00000000)
Is this interfearing with loading and running the Anti Malware software ? What can I do to get a clean Safe Mode start up

Advanced troubleshooting for "Stop error code 0x0000007B (INACCESSIBLE_BOOT_DEVICE)" errors in Windows XP

You may receive a "Stop 0x0000007B" error message if your computer is infected with a boot-sector virus. If the problem is intermittent and you can start Windows, check your computer for viruses.

Is this what you see on your screen after you selected safe mode?

And what version of Windows do you have?

OK, then follow the instructions in the last link quietman7 posted. This is my method to restore the missing registry keys that are need to boot into Safe Mode.

Is fixing the Safe Mode matter a prerequisite to any of the other clean up processes ? I'm assuming it is but you are the expert. Until MS stopped supporting XP and while I was using Firefox I never had any infections. My anti-virus service eAcceleration Stop Sign always turned up zero files to quarantine. They even told me they never had infections in clients when Firefox is used.

No, it is not a prerequisite.

 

But you didn't tell us that your machine is infected. We are merely giving instructions to fix your problem, e.g. boot into Safe Mode.

 

If your machine is infected, or you suspect it is infected, start a new thread in "Am I Infected" http://www.bleepingcomputer.com/forums/f/103/am-i-infected-what-do-i-do/

 

If you don't believe your machine is infected and you want to restore Safe Mode, apply the registry fix explained in the link: http://blog.didierstevens.com/2007/02/19/restoring-safe-mode-with-a-reg-file/

ok. You meant the 3rd link in quietman7's post. I will have to save it to a USB drive using another computer. Explorer must be infected too.

FYI: There's malware that not only deletes the SafeBoot registry key (essential for Safe Mode operation), but also monitors and deletes it again when it is restored.
