I'm having almost exactly the same problem.
First, AVG indentified the virus Trojan horse generic 14ADYJ located in system32\drivers\agp440.sys and it couldn't remove it because it was on a critical windows file.
Malwarebytes didn't even identify this virus.
I copied the same file from the windows XP installation CD onto the folder and that way I replaced the infected file. Just then I re-started the computer and inmediately run AVG again to check whether the virus had survived.
Instead of that virus it found Packed.Protector.C, located in two places: in system32\dllcache\ntfs.sys (which was moved to Virus Vault) and in system32\drivers\ntfs.sys was could not because it was again a white-listed critical file.
I believe then both viruses are related, if they are not the same one with different names. Can anybody give any info, if not about how to remove them, at least about what these viruses do? so as to be warned and watching out when using my computer. Thanks.
