I get this message : "MBR sector of the 1. physical disk-Win32/Mebroot.H Trojan" & NOD32 can't clean it nor delete it. I have two HDD with 3 partitions and in deep scan it shows this message for all three of them.But (this is where it gets interesting) when i disconect the hard disk i use only as storage, and rescan the disk containing windows OS, non "Win32/Mebroot.H Trojan" message appears. The same thing appears when i connect my memory stick. Any suggestions??
