If antivirus software is not installed, HP recommends you install antivirus software. New viruses are created and released often, and without antivirus software, the files and folders on the computer are at risk. If you found antivirus software on your computer in the previous step, skip to the next step.
Many HP computers with Windows come with Windows Defender. Other HP computers might come with free trial versions of other antivirus software. These trial versions are usually limited versions that can be kept up to date for a specific period. After the period expires, your computer becomes more vulnerable to new viruses and security threats. It is important to upgrade or refresh the subscription to keep virus definitions current and continue protecting your computer.
If your device did not come with antivirus software, check with your Internet Service Provider (ISP). Many ISPs offer free or inexpensive antivirus software to their subscribers.
note:
If you have antivirus software installed, but want to install different antivirus software, make sure to remove the old antivirus software before installing new software. Having multiple programs installed might make the computer slow, erratic, and potentially unprotected.
