Windows XP will not boot after login screen (explorer does not run)

My computer was fine at first, I wanted to install the programs for my HP All-In-One Printer, during installation, the system was starting to slow down due to "WinFixer" ads, so I was looking for ways to remove them, as they were slowing down my system, I came across XoftSpy, which seemed to work ok, and removed alot of stuff from my system, next thing I knew, everything froze and I couldnt run anything, I went to do a restart and after I logged in, the system would not boot up, (explorer.exe will not run). I tried to run some other programs such as Windows Restore, but no luck, I also try to use my XP disk to do a repair, but that didnt work either!! What should I do?!

Hi cg0789,

Can you enter in safe mode ?

If so run Ewido :

Download, Install, Update the Database definitions and do a scan. Post the report in here ...

After that Let's take a look at your system :

Go to http://www.merijn.org/files/hijackthis.zip and download the file, run and save a log file.

Run a command Line and try this:

and restart the computer

"Windows File Protection could not initiate a scan of the protected system files.

Okay, here is what I just found out, I tried to run "mmc" to resolve the "sfc /scannow" issue, and it said that the registry is corrupted, (I think that may be the "root" problem), when I was using XoftSpy it removed several registry entries, probally causing all of this chasos! I still have the problem, any idea how to restore the registry?

cg0789Author Commented:
I am also able to access the registry.

Hi cg0789,

If you have a backup of the registry, you can restore that :

http://support.microsoft.com/kb/322756/en-us

But you give me one ideia :

Download this file :

http://optatum.paginas.sapo.pt/cmds/scan.zip

Execute and restart the computer .....

If you prefere, you can do that file, just open the notepad and copy paste the following:

@Echo Off

SET KEY=HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\RunOnceEx

REG ADD %KEY% /V TITLE /D "Windows File Checker" /f

REG ADD %KEY%\000 /VE /D "Starting Explorer" /f
REG ADD %KEY%\000 /V 1 /D "%SYSTEMROOT%\explorer.exe" /f

REG ADD %KEY%\001 /VE /D "Windows File Checker" /f
REG ADD %KEY%\001 /V 1 /D "%SYSTEMROOT%\System32\sfc.exe /scannow" /f

EXIT

Save the file with the name scan.cmd and execute the file one time.

Restart

What happens ?

Okay, it seems like those commands worked, now when I try to do the sfc /scannow command it works, but doesnt scan like it just goes to the next line in DOS. But no error. :-(

cg0789Author Commented:
It seems like everytime I try to run explorer it kills itself. Maybe its a virus?

cg0789Author Commented:
Okay, I got 'sfc /scannow' to run, now I gotta track down my Windows XP Pro CD so it can properly do the scan, (ill post back tomorrow when I get it! At least we are making progress!

I decided to do a quick backup of my system just in case, all of the sudden I got this pop-up

"McAfee VirusScan
McAfee ActiveSheild has found a suspect file on your computer.
McAfee strongly recommends that you scan though your computer now."

Does this mean I got a virus? Once I finish the backup, I will scan the files on this machine with the scanner you gave me :-)

Hi cg0789,

Yes :))))

>>McAfee strongly recommends that you scan though your computer now.

Maybe yes, and maybe now .....

McAfee could thing that cmd is a virus because he is calling system files, like explorer.exe and sfc.exe .....

But don't worry with that now ....
