That's about it but i like to experiment with different software to know what makes them so "Special" . But using a special word does not cut it so i am still in search of something that would change the rules of the playing field
It looks good! As long as you know what you're doing, Windows Defender should hold up fine. I wouldn't depend on it. I would look for something with a better detection rate. Then again, I don't use a AV.
Windows Defender is enhanced in Windows 10 and guarantees a good level of protection in a normal use of your computer without installing any third party antivirus.
As @frogboy says it is important a backup and recovery plan to ensure data and OS security.
