BleepingComputer.com: Tutorial Finding My Files

I am getting assistance from Malwarebytes helpdesk for an apparent hijacking trojan that I have.

I installed ComboFix aper the techs instructions. He has now asked me to look for a combofix text file at c:\combofix.txt. I probably could find it when I was using Windows XP, but for the life of me I can't find it using the Vista operating system. Where do I look? I need a tutorial on finding all my C:\ files. This should be easy but Vista seems to be hiding them on me.

HELP!

hi,,, click on vista start menu orb>click computer>click on C: drive>click on program files>click on combo fix program file and look for the file they said,,,,,
also with vista if you index the C: drive then just type "combofix.txt" into the search box in start menu and it will come up instantly
good luck.
