Best Free Antivirus for Notebook?

New laptop, Do you have a recommendation for me, which free antivirus program is good…

Windows 10's own Defender combined with a well-functioning brain that does not click on dubious things like Noodle Enlargement Pills commercials.

Under Windows 10, there's no reason to install anything in terms of security. The on-board Windows Defender has this year repeatedly achieved in terms of recognition rate best ratings in various reviews and thus performed better than some paid software. Only in terms of handling and special attitude for behaviors offer other programs more. But if you just need a secured system without bells and whistles, currently drives with on-board resources best.

For legacy systems, Bitdefender Internet Security would be the most efficient choice and the biggest advance over free usage, with Avira Antivir often ahead of the pack.
