Confirm the Windows version and processor architecture, available RAM and storage, internet access, the number of devices you want to cover, and which premium protections matter to you. If you use Windows 11 on ARM, note the feature exceptions. Also review the subscription length, renewal option, and whether mobile devices are included in the selected plan. Finally, compare AVG Internet Security with simpler antivirus-only options so you are paying for the extra web, privacy, and account protections you will actually use.
