What version of Windows are you using?
What version of Eraser are you using?
Does the file 'C:\\windows\system32\1223570772.(null)' exist, if so what is it?
Try renaming the file in question to something like <filename>.bak and see if the problem persists.
I am using Vista Ultimate 32 bit. I have deleted/erased every single registry entry for Eraser. I used two different registry cleaners and everything is gone related to Eraser. However the problem is with the: HKLM\Software\Microsoft\Windows\Current Version\Run Once. This key keeps recreating itself with "Windows\System32\Eraserl.exe. I have completely deleted this entire "Run Once" entry several times, yet it keeps recreating itself. There is no file Eraserl.exe. in the Windows\sytem32 folder. It seems to me there is some kind of adware, spyware, virus that came with the Eraser program that keeps recreating this key. Please help. Thank you.
