Hi Julie Marie,
I hope, besides the cump virus thingy, that you are doing well.
I'm not a super techy person, but have some skills as they say. I would research the virus online, get any patches, (on a removable medium) particular to the OS you're running and update them to the primary HDD. After the secondary/crashed drive is connected to the CPU, SCAN AND REMOVE any threats with an AV application which has current protection for the threats you killer virus attacks before you try to explore any data. It seems like good AV info has been mentioned previously.
I've never treated a totally crashed drive, but have rescued more than a few friends systems with viruses less malignant than yours sounds. Do you know what name it has?
I hope this helps you some.
I hate cumputahs.
