Drive 0 is the first hard disk drive you have usually the one you normally boot from.C,d,e etc are the partitions on that drive.Try going to the free online scan sites such as www.trendmicro.com or www.symantec.com and get a scan done.
Try to google for the virus ands for virus removal tools.
"Bloodhound" means it is a heuristic detection. Heuristics can produce false positives. So I agree with the suggestion to try an online scan to see if any other scanner verifies a boot-sector infection. You have to have ActiveX enabled in IE to use these scans. Attached is an html file with links to the major online scans available to you. Good Luck!
Bloodhound is not the name of a virus, but a message displayed by Symantec's Norton Anti-Virus when it thinks it may have found a new virus. You can submit the suspected virus to Symantec for further analysis.
