A patch is simply a bug in your computer. You can make up for your loophole by mending it. Figuratively speaking, it is a patch. It doesn't matter much if you delete it, because your patch has been laid, and 360 useless programs have been deleted. 360 downloaded patch on your installation disk D:\Program? Files\360\360Safe\hotfix folder, look at the picture, it looks like this. If you want to restore the deleted files, you can search Recuva, and you can restore the deleted files. I hope I can help you.
