Murray wants to know if he needs to install an antivirus for Windows 10. Leo says no. Windows 10 has its own antivirus that is automatically turned on called Windows Defender. But also, viruses spread so fast that antivirus software can't really keep up. It can't protect against 'zero day' exploits. Antivirus is really only a backup. The first line of defense is online behavior. The number 1 priority should be to keep the computer updated.
Alan just installed Windows 10 on a few computers and wants to know if there's any reason to install a third party antivirus program with it. Leo says that Google has done a study about this, and they've found that most security experts believe antivirus software gives a false sense of security and doesn't guard against zero day exploits, which are the real threat now.
Jeff recently bought a Windows 8.1 computer and it comes with McAffee. Does he need it? Leo says no, Windows comes with a far better antivirus utility called Windows Defender. McAffee is put on the computer because the company makes money putting it on every computer. He should uninstall it immediately and activate Windows Defender.
Jim is buying a new Dell computer and wants to know what antivirus software he should get? Leo says first, an antivirus can't protect him against yourself. It should just be used as a backstop. He will be the first line of defense.
Windows actually has a good antivirus solution built into Windows 8 called Windows Defender. That'll work just fine as long as he keeps it up to date. He should also make sure he runs as a standard user, not an administrator. And don't click on links in emails.
Billy is getting a new Windows 8 desktop and wants to be sure he sets it up with the proper security. Leo says that Microsoft is now bundling Windows Defender (formerly called Security Essentials) with Windows 8, so he'll be protected as long as he keeps it up to date. There are other things he can do to protect yourself more, though:
Leo says no, it's fine. Unless he has Microsoft Security Essentials, then he should uninstall that first. Competing AVS software don't play well together. (Disclaimer: ESET is a sponsor).
