Definitely Windows defender is a good product.
The problem with Microsoft is that they have limited useless live support. But defender is a really good product. I tested it on an old computer by going to questionable sites. Downloaded a virus and although i had to restart windows in safe mode, defender got ride of the virus and protectec the computer hard drive.
I trust the product, just dont go to shit sites on a computer with important info, use a cg
Cheap lop top for that.
