Back when Microsoft introduced Windows 11, it proclaimed the brand new working system to be essentially the most safe model of Windows but. The firm’s necessities actually suggest that Windows 11 outdoes its predecessor, given the necessity for a trusted platform module (TPM) 2.0 and Secure Boot with a view to obtain full compatibility—in addition to a guarantee of future security updates.
But Microsoft touting Windows 11 as safer is having an unintended impact. Some individuals now imagine they don’t must do something past assembly these {hardware} and safety necessities. And that’s not true.
TPM and Secure Boot solely defend in opposition to two forms of threats. A TPM shops data associated to encryption or authentication (like Windows Hello biometric information). To maintain it secure, it screens your {hardware} configuration—if it notices a change, it’ll lock you out till you present a restoration key or use another methodology for login. For its half, Secure Boot makes certain that the signature of the BIOS (technically, UEFI) drivers and working system are legitimate and trusted earlier than management is given over the OS.
These defenses stand in opposition to newer sorts of assaults, however older, extra generally recognized threats nonetheless exist, like malware concentrating on your exercise throughout the working system. You most likely already know how you can defend your self in opposition to these risks, and in Windows 11, you need to nonetheless be vigilant. Once you’ve obtained these locked down, you possibly can then transfer on to extra enjoyable issues, like Windows 11’s best hidden features or the six new features you should try in Windows 11.

What you select to do in your PC immediately impacts your degree of danger. Clicking on hyperlinks, downloading recordsdata, putting in applications, or plugging in exterior USB drives with out first occupied with the place they initially got here from—and what they could achieve entry to—can create the issues that safety {hardware} and software program attempt to protect you from. Just as a result of the one who handed it to you is a trusted supply doesn’t imply the hyperlink, program, or drive itself is reliable.
The identical goes for giving out private data that can be utilized to get into your accounts, like your delivery date, location, telephone quantity, social safety quantity, and the like. This is much less to do with Windows safety particularly, however it may possibly create complications with entry to your linked Microsoft account and different companies. In an identical vein, don’t retailer this sort of delicate data in a non-encrypted file (e.g., Word doc) or share it over non-encrypted types of communication like electronic mail or textual content message.

Those unhealthy hyperlinks you would possibly by chance click on on, or these applications you downloaded pondering they had been legit? Yeah, you continue to must be careful for these. The greatest protection in opposition to these threats is to watch out in your every day routine, however you possibly can’t chase away all the things. Sometimes you’ve an oops—or typically you do nothing in any respect, and there’s a found vulnerability in {hardware} or software program. (Remember that point when CCleaner, a well-regarded program, pushed a compromised update?)
So sure, you still need antivirus software in Windows 11. That mentioned, Microsoft supplies an answer as a part of the working system: Windows Security. It’s a great primary possibility that ought to work positive for individuals who navigate the web with safety in thoughts. Just ensure it’s turned on; it ought to be by default.
You can select to as a substitute set up third-party software program, however it’s not strictly essential. Some PCWorld employees members pair Windows Security with a extra malware-specific program for just a little extra protection. But two applications is essentially the most any of us do—you don’t wish to go overboard on layering them, as they will find yourself preventing with one another and canceling out the general effectiveness.
Side notice: For anybody questioning if virtualization-based safety eliminates the necessity for antivirus software program, it doesn’t. VBS is a special sort of safety than antivirus. Antivirus scans for user-level malicious applications, whereas VBS screens for operating-system (kernel-level) threats. You may be pondering of digital machines, which you’ll create in Windows 10 and 11 to run applications that appear suspicious however you wish to check out anyway.

Having no firewall software program in your PC is just like leaving all of a home’s exterior doorways vast open. Incoming ports are left utterly uncovered, which implies anybody on the web can then try to take advantage of companies in your laptop obtainable by way of these ports. As you’ll guess, if such probing is profitable, issues may result.
A firewall blocks entry to these ports—it’s the equal of putting one thing round your own home in order that nobody can get in. Someone can ping your PC on these ports (the equal of knocking on the door), however they’ll by no means get a solution. They can’t make mischief because of this.
Many house routers have a built-in {hardware} firewall, however you possibly can’t depend on that as the only technique of safety in your PC. You nonetheless need particular person units to be guarded, not simply the community as an entire. Your house community might nonetheless develop into compromised. More generally, although, if you happen to’re a laptop computer person, it’s the opposite networks you hook up with while you’re not at house that may very well be weak.
The excellent news is that, identical to its predecessors, Windows 11 supplies ample built-in firewall safety. Just ensure it’s turned on within the Windows Security app.

Breaches and leaks are an unlucky a part of common life these days. Windows 11 may be safe sufficient, however the password you employ in your linked MIcrosoft account is similar as for different companies, the working system’s protections aren’t going to avoid wasting you from unauthorized account entry.
First and foremost, don’t reuse passwords. You ought to use a robust, random, and distinctive password for each service and web site, and also you also needs to change your password for wherever that’s reported a breach or leak. A password manager can maintain monitor of all of these random character strings in a method that’s secure and doesn’t require you to recollect them individually. And since free password managers exist, there’s no excuse to not do it.
Enabling two-factor authentication additionally helps shore up your defenses in opposition to information leaks. Even in case your password or restoration data turns into public, including a second step to the login course of can thwart makes an attempt at accessing your account. The most safe methodology is a {hardware} dongle, however most individuals will discover utilizing a cellular app that generates a code the perfect steadiness between safety and comfort. Even 2FA over textual content message is best than nothing.

On any community, it’s attainable to see what information is being requested and despatched to particular person units. (This is named packet sniffing.) The extra open the community, the simpler it’s for this to occur.
As you would possibly guess, public Wi-Fi has the best potential for this sort of exercise. Any stranger can hop on and see what gadget and purposes you’re utilizing, websites you’re visiting, and your general conduct throughout that session. And if the information is unencrypted, they will additionally see the precise data you’re transmitting as properly, which doesn’t bode properly if any of it’s delicate.
Since you could be compromised with any of that data—you’re not nameless even when on encrypted websites—it is advisable route that site visitors in a method that received’t reveal an excessive amount of about you. Enter a Virtual Private Network, or VPN.
A VPN creates a safe tunnel by way of which all of your site visitors is funneled. Only you and the VPN supplier know what you’re as much as, somewhat than any variety of individuals on the identical community as you. Use a VPN in your units (PC, cellular, pill) everytime you’re on public Wi-Fi, or when it’s in any other case necessary to maintain your exercise non-public.
When selecting a VPN service, maintain a couple of issues in thoughts. First of all, a free VPN prices nothing for a motive—you’re the product. If privateness is what you need, you’re not going to get it with a free supplier. Second, select a paid service that’s well-regarded. Policies on logging and information retention ought to be clearly spelled out, for instance. (Need a fast set of strategies? Check out our checklist of the best paid VPNs.) And lastly, a VPN doesn’t make you utterly nameless. At minimal, the service is aware of the gadget you related with and the place your site visitors requests originated.
