Re: Getting hacked and lost everything
I see two possibilities here as to why it's come back.
The first is that the infection wasn't completely destroyed when you got re-installed. If the MFT wasn't deleted and reformatted a rootkit could still be laying in there. A full format, not the quick one that many re-install disks default to, would be needed to clean that up.
The second is that you re-installed something, or re-copied over an infected file. Ditch McAffee and look into Kaspersky or NOD32 like MMM recommended (NOD32 is my favorite). Using those, scan every document you happened to have a copy of before putting them back onto the computer, and if possible set the program to scan external devices when they are plugged in to prevent auto-play infections. Do the same with executables you download to re-install your programs. Assuming it's not a rootkit like I mentioned before, it's likely that one of those are re-infecting you.
