Windows 10 does come with windows defender just as in windows 8 and 8.1 . It does seem to do a fair job on keeping the system safe. I should remind everyone that no virus software will protect a system 100% of the time, so always back up your system. I did try installing free avg 2015 on the windows 10 system and it seemed to have some issues. It kept coming up and wanting to reboot the system, therefore I uninstalled it. Below is a list of compatible antivirus programs working so far with windows 10. All I can say you have to try for yourself. If you are looking for a different AntiVirus Software check out the store below the posts.
