If I format or erase my hard drive, will it remove a virus?

Computer VirusIf your computer is infected with a virus, formatting or erasing the hard drive and starting over will almost always remove any virus. However, keep in mind if backups of your computer have been made that contain a virus, your computer can be re-infected if not protected by an antivirus program.

Note: If other disks in your computer have a virus, or if your computer is connected to an infected computer on your network, your computer could be re-infected if not properly protected.
