Misika,
Whenever posting questions on these forums, please give us as much information as possible about your computer. Depending on your issue, we might need the operating system, processor speed, amount of RAM installed, brand name of the computer, (if there is one), and any EXACT error messages you are receiving, and the EXACT version of Virus Scan, plus the scan engine and virus defintions that you have installed. (RIGHT click on the McAfee shield, or red "M", in the lower right corner, choose "About Virus Scan".) The more information you give us, the better informed our answer will be.
It sounds like you're trying to reformat the C drive while in Windows. That doesn't work. Instead, have you checked the link below:
Toni Hackler's: How To Fdisk and Format Drives
Then again, IFf the only problem is that you can't connect to the internet, you may not need to reformat the computer. Have you tried using the program below:
