XP Doesn't Boot Again after Installing Norton Antivirus

Hi,

 

Early this month, I purchased, downloaded and installed Norton Antivirus on my notebook (which is running XP Home, but I've forgotten which SP) and the XP never boots again. When I boot it in the Safe Mode, my machine hangs on agp440.sys. After I disabled the agp440.sys with the XP recovery console (as a lot of people on various forums suggested), it now stops at mup.sys when during reboot.

 

Would anyone pls. suggest how I get boot up my computer again?

 

Thanks,

Jonathan

Hi,

 

Did you try the Last Known Good Configuration option? If that does not work, I suggest you to boot from the Norton Bootable Recovery Disc, and then run a scan. You can find the instructions in the following Knowledge Base article:

Hi Jonathan

 

If you use your XP CD you should be able to boot to the Recovery Console to help fix your system.

Be careful about disabling drivers.  According to this information, as you disable one driver, the next one in turn will do the same thing.  The best recommendation ws to run a chkdisk/r.

 

"I grabbed my wife’s laptop and did some Google searches on agp440.sys and found that this appears to be a red herring. I believe it just happens to be the last of the drivers loaded before services start being initiated.
Several folks did some experiments where they renamed or otherwise disabled the agp440.sys driver and found that the failure then occurred on the next previous driver."

 

It seems to be mainly a hardware related issue.

Hello jonchan

 

Welcome to the Norton Community

 

Did you have a clean system before you installed NAV onto your notebook? Did you try to install it on a system that was already compromised? What security program did you have previously and how was it removed? What are you using for a firewall?

 

Here is some information about agp440.sys from ThreatExpert

To me, it looks like you have some malware that needs to be cleaned up. Since system files seem to be involved. it's possible that you may have a rootkit.
