Anti-Virus software & "locked files"

Discussion in 'Computing' started by John Phillips, Dec 29, 2006.

  1. I notice when Nod32 does a virus scan, "locked" files are not scanned -
    "Cannot be accessed".

    By "locked" files it appears to mean current system files and those of
    any proggys running at the time of the scan.

    Do all anti virus software have this issue, and is it something to be
    concerned about?

  2. does NOD run a "process scan" before it starts scanning your actual
    files? be a fairly bad mistake if it didn't.

  3. Well if it does, I can't see anywhere that this is actually stated, or
    an allowable selection.

  4. No that would happen with all anti virus and spyware checkers.
    Also with MS chkdsk, defrag etc.

    If you have a history of being infected by virii or spyware then close
    all programs while the checking is current. Otherwise don't lose any
    sleep over it.

  5. Thanks.

    Similar reply from NOD as well.

  6. I agree with Stuart. Any app can have this problem, if it tries to access a
    file which is already held open by another process. Ordinary apps like word
    processors usually don't try to do this: it's mainly the realm of disk and
    file utilities, antivirus etc.

    On XP and later, you can see what files are being held open by running the
    "openfiles" command at a command prompt. Alternatively, you can use
    SysInternal's "handle" utility:
