Do I need an AV on a new Win 10 laptop?

Actually, I have given up even scanning with malwarebytes as it has never detected anything that Defender did not pick up. That is not to say it will not of course.

Even when Defender was less advanced, it was only minor stuff that go through, worst being my chrome browser getting hijacked. A quick uninstall and reinstall usually sorted the issue. Of course, if Edge gets hijacked, not so easy.

That's a good tip about enabling Defender PUP protection...

Thanks @Steve C
Yes, beats me why the settings for such a useful additional protection are only visible to Enterprise users....

OK.

• My professional opinion: All you need is Windows Defender and Windows Firewall, in addition to being careful (not open attachments from unknown senders, not reply to messages asking account credentials or other personal information, avoid pirate torrenting and warez sites, only install software from software maker's own site, and so on).
