Is reformatting my C drive my only option left?

it is the only sensible option, if you value the security of your system/data
because the system is severely compromised
→ you have several active backdoors on your system,
which allow complete control for a malicious user

see for yourself → Hijackthis-Analysis:
http://hijackthis.de/logfiles/4c0397ab137ed0e373606129306ff83f.html

several of the red nasties are active Backdoor-Worms !!

if you don’t want to/can’t format:
For a start:

  • fix everything with hijackthis that’s marked RED in the above analysis,
  • and also the F1-entry
    (fixing means putting a checkmark to the respective line and then click “fix checked” )

BEFORE fixing, kill any of the processes/files corresponding to the red-entries
in hijackthis via Config → MiscTools → processManager

after fixing, schedule a boot-time scan & reboot immediately

but keep in mind that only a format & PROPER re-install of WIN
can assure that your system is clean again
→ reread the above mentioned link “VirusRemoval” → BACKDOOR
