Hi Roypowls!
If you have latest updates Windows 10 delivers comprehensive, built-in and ongoing security protections that you can trust – including Windows Defender anti-virus, firewall and more. By staying up to date, you’re assured of the latest features and protection – at no extra cost to you...
If you still doubt or need extra edge internet security with more features you can use antivirus like Avast which starts from free and is as good as bunch of paid antivirus!
If this was helpful please click on "YES it solved my problem", it really motivates me towards helping more and more...
Have further question or doubts? Please feel free to ask! Waiting for your reply! :D
