@JosieMonroe You probably don't need a third-party antivirus. Windows Defender is actually reasonably good; as long as you're not downloading from sketchy sites, that's likely enough protection. Besides, the free versions of many antiviruses are worse than Defender, and they love to flag bogus threats to try to convince you to buy the paid versions instead.
Still, please check the Task Manager's background processes list to see whether you might in fact have an antivirus running. Many if not most laptops do come with one, and sometimes it activates itself.
Your dxdiag does have a number of Windows update errors, so it's a good idea to clean those up before going further. Please run a couple of basic checks of your Windows system files:
- Hit Windows key-X
- Choose either “PowerShell (Administrator)” or “Command prompt (Administrator),” whichever option is offered
- Inside the window that appears, copy and paste “DISM.exe /Online /Cleanup-image /Restorehealth” without quotes into the window, and enter
- The system will start validating soon. If it throws an error, please list it here
- After it reaches 100%, hit Windows key-X again
- Again, choose “PowerShell (Administrator)” or “Command prompt (Administrator)”
- Inside the window, copy and paste “sfc /scannow” without quotes into the window, and enter
- Post the message you receive here
Restart your computer, hit Windows key-i, select Update & Security, and click the button to check for updates. If any install, restart again afterwards.
The driver for your graphics chip is a bit old, which normally wouldn't be a problem, but it predates Windows 11 by enough that it might not be compatible. So it's a good idea to update that as well, but best if HP offers one for your laptop. To check, please go here:

Enter your computer's serial number, select Windows 11 if asked, and you'll land on the driver download page for your laptop. Please link that page for me; I can't be sure I'm looking at the right one from the product name in your dxdiag. The download page doesn't have any info about your own system, just the overall model.
