A consideration for a FREE (and very good) anti-virus program is Avast. Bob Rankin outlined what is new for Avast 2016 in his recent article. PC Magazine ranked Avast 2016 No.1 for malware blocking. |
Of course, there are many options from which to choose. You can review what the "How To Geek" has to say about protection for Windows 10.
No matter which anti-virus you choose, you must remember to keep it updated - not only for your protection, but for the protection of those with whom you communicate.

Stay Safe!
