  • Used to prevent, detect, and remove malicious computer viruses
  • Has to run at least once a week

  • Protect your computer or identities

In case you get a virus, shut down computer and boot it up with the antivirus installation disk. If the software does detect a virus, you may want to research to determine if the antivirus software will eradicate them completely or whether you will need to take additional steps to eliminate the virus. You can also go to the website of the antivirus company and they should have step by step instructions.
