I just got a threat alert: Object: MBR sector of the 6. physical disk Threat: Win32/Mebroot.CA trojan Comment: Error while cleaning - operation unavailable for this object type Questions: 1) How do I figure out which is the 6. physical disk? 2) Is this a sign that there's just a remnant (I think/thought I eradicated a Mebroot back in May) since there are no other reports re. processes or other stuff related to Mebroot? 3) What do I do to get rid of it? Thanks for any help!
