Information

Is your computer still behaving badly? If you have not already, please try cleaning all viruses and spyware (http://www.antivirus.vt.edu/reactive/viruses.php) from your computer. However, it may have a virus, spyware/adware, or operating system problems that can not currently be repaired. If so, you may need to reformat, reinstall the OS and applications, and secure the computer. For assistance with formatting a computer and reinstalling Windows, contact either your computerís manufacturer or a local repair shop. Or, do it on your own. Either way read the following so you understand the process.

Before the reformat:

  • IMPORTANT: Disconnect your Ethernet cable from the portal.
  • Locate all your OS, application, and driver CDs. If your vendor supplies a system restore CD, locate it.
  • Backup all your important files (http://www.antivirus.vt.edu/info/backup.php) including email and bookmarks. Search http://answers.vt.edu for the location of these files. Back them up to a freshly formatted Zip disk, writeable CD/DVD or external harddrive. You might want to make two copies.
