    Hey people,
    Has anyone run into an Agent.ac trojan infection with NOD32? I have a computer with an agent.ac trojan infection. NOD cannot clean or delete the file so a manual removal was attempted. AMON gives the location of the file but whenever the folder is viewed (even from the command prompt with the " attrib " command there's nothing there). AMON continously alerts to its presence but they're nothing there, even an on-demand scan with NOD32 picks up nothing. . . Am confused. . . - a sample of the log is below. . .
    Anyone know anything about it?

    It says in the log the file is locked. How do you unlock it so you can delete it?


    Found a discussion. HERE and here

    "I suggest you drop an email to support@nod32.com along with the registry file exported as well as information about the operating and file system you use (FAT32 or NTFS)."

    I noticed there is a free removal tool here which may or may not help.

    You could try this manual procedure found at Trend Micro (TROJ_AGENT.AC):

    They also have an automated fix tool at the same link. I hope that that this is the same variant as yours and is helpful to you. I haven't had to face this particular nasty.

    have you tried running NOD32 scanner in safe mode or put hard drive into other PC and scan that way,

    or

    changing ownership of folders/files of those specifice locations.
