Better than the restSo you download these expensive antivirus programs when you buy an MS computer or laptop, which is guaranteed to slow your computer down. Windows comes with the best antivirus software, which works seamlessly with your computer and stays 100% up to date at all times.

Still trying to figure it all outI’m happy to have Microsoft Defender. It lets me know when security issues might arise. However, I still have a few kinks to work out.
