Hi. I currently have Spectrum cable/internet. They just replaced McAfee antivirus with F-Secure Security antivirus. However, I am migrating from Spectrum cable/internet to T-Mobile 5G and T-Mobile does not provide any antivirus for the internet. Since the McAfee will likely stop working soon, and I will not have access to F-Secure on my Windows-10 desktop PC, would it be sufficient for my desktop PC to just activate the free Windows Defender? I had read somewhere that with being a cautious user on the PC, that Windows Defender will provide enough protection. Thanks, John.
