    Yes, you should be concerned. The MBR (Master Boot Record) is the file that tells the computer how the drive is partitioned and how to load the OS. If it is missing or corrupted, you won't be able to access the data on that drive.

    The big question is why it is corrupted. A virus targeting the MBR is a possibility & those can be difficult to detect and remove. But, don't rule out a hard drive failure due to heat or time.

    Maybe you have a memory card reader with no card actually inserted?

    this is my PC http://reviews.cnet.com/desktops/hp-pavilion-elite-hpe/4507-3118_7-34191436.html
    It has a card reader that suports these


    Supported Flash Memory Cards SD Memory Card,
    MultiMediaCardplus,
    CompactFlash Card type II,
    miniSD,
    MultiMediaCardmobile,
    RS-MMC,
    Memory Stick,
    xD-Picture Card,
    CompactFlash Card type I,
    Memory Stick PRO Duo,
    SmartMedia Card,
    MultiMediaCard,
    Memory Stick Duo,
    Memory Stick PRO

    Is this the cause then?

    The system works properly,at least until now.just those error messages during the scan.

    Simply wait until ESET responds further.

    Hello,

    From looking at the HP Pavilion Elite HPE-400f Desktop PC Product Specifications, it appears the unit has a "15-in-1 Memory Card Reader" in it, which is what is leading to the report of MBR's not being found when ESET Smart Security tries to scan them without a memory card being present.

    There are a few ways in which you can test yourself to confirm this:
    • Disable the memory card reader by either physically disconnecting it, disabling it in the BIOS, or under Microsoft Windows by whatever means Hewlett-Packard recommends and then re-run the scan.
    • Insert media into the memory card reader and then re-run the scan. Even with just one type of memory card installed, you should see one of the "MBR sector of the n. physical disk - error opening [4]" message go away.
    • Perform a manual scan of each drive letter until you come across the ones which are triggering this message.
    As my colleague Marcos noted, this is fairly normal behavior for when a memory card reader is installed without any media being present in it during a scan operation.

    Regards,

    Aryeh Goretsky
