    I noticed that everyone had a PNF file associated with the
    However, in my case, it was found an INF's the path... c:\windows\inf\oem8.inf
    My ZA settings are setup to Quarantine an infected file (so I can make the decision to delete)...I've never been comfortable
    giving any software the ability to automatically
    delete anything without my knowledge.

    Any idea what I should do with the oem8.inf file?

    Can anyone confirm what this file is for?
    I tried searching the inet for its purpose, but didn't find a clearcut description.

    I also had this problem and deleted oem8.pnf, oem9.pnf and a thinkpad.dll file (or similarly named file from the system32 directory) as recommended by ZoneAlarm.

    Got the black screen, but was able to boot with F5 and selected 'boot system from last known good configuration'.

    System appears to be working ok now, but checked and the above files are still deleted.

    My question is:

    What are these files?
    Is my system ok to run without them?
    How does one obtain the files without doing a system restore (my laptop came with windows XP preloaded so no windows discs unfortunately).

    Thanks in advance!

    Hi, IGNORE the false positive- a PNF and INF are the same thing except the PNF is more binary.

    I hope you can help me out. I having this problem too except I didn't delete the file, I quarantined it and after learning it was a false positive, I restored it but now, I assume ZA has already deleted the registry keys, but fortunately I had copied down the keys and I am wondering if I could manually re-enter the keys into the registry through "regedit" because I want to avoid using system restore since my experience with it was chaotic and egregious. I'm using window xp btw. Thanks in advance.

    Original msg:

    Please see User Forum Thread titled ZA Anti Spyware thinks oem8.PNF is Trojan

    Should Trojan name Win32.Trojan.Dropper.Small.156 be removed from your Anti-Spyware definitions list so that it doesn t come up in the Scan Report ?? Or at least update the ZA webpage linked to warn users that it may cause problems if quarantining it before deciding if the files are needed, when users click on the More Info button.
