Don’t Open Links in Emails That Lead to a Login Screen

It’s pretty common to receive an email with a link or a button that leads to a login screen, but you shouldn’t use them. It’s all too easy for a scammer to create their own fake login screen, email you a convincing looking email with a link, and then steal your password using it.

Instead, if you click on a link that lands you at a login page, close the browser tab or window, open a fresh one, and type in the address for the website yourself (or, if you’re using an app, re-open it). Once you’ve logged in to the right website, you can check your notifications from your account there.

Use Strong Passwords and Two-Factor Authentication (And Don’t Share Them!)

Google

You should always use a unique password for every website, service, or app you use, and make sure they are strong .

If you re-use passwords for different services and one of them is breached, the hackers will try the password they stole on other sites to see if you reused it (this is called “credential stuffing “). If you give your logins to a friend (even for your Netflix account), it’s out of your control, and they might accidentally disclose it to someone else, leading to additional accounts being compromised in a chain of attacks.

Of course, you can’t be expected to remember all of these different passwords, so you should use a password manager to keep track of them. You should also enable two-factor authentication wherever possible , so that even if your password is leaked, attackers still won’t be able to access your accounts.

Don’t Ignore Windows Security Prompts (UAC)

Every Windows user has seen these annoying security prompts from User Account Control (UAC). Whenever a change needs to be made to the system, one of these alerts will pop up and ask an Administrator to approve the action. While they’re annoying, you shouldn’t ignore them, and carefully read the information they display before dismissing them or allowing the change.

This is because viruses and malware will usually need some kind of Administrator access to burrow deep into your system. These prompts are designed to stop them from doing this. Make sure you check that the application requesting access is from a verified publisher, and from a source you trust. Importantly, make sure you understand why the prompt has been triggered: if a UAC security prompt pops up from an unknown program or when you haven’t taken any action, you should decline it and check your system for viruses .

Keep Your Work and Private Life Separate

You don’t want your employer to know all the details about your personal life, and your employer doesn’t want you to be accidentally leaking company information through your social media profiles. Keep your work and private lives separate by using different email accounts and profiles for each. This helps prevent information from leaking, for example, by making it more difficult for you to accidentally put your dating schedule in the work calendar, or email a sensitive financial report to your yoga class.

The most effective way to do this is to create separate user accounts on your computer. You can also use Firefox Containers or Safari Profiles, or isolate different activities by using a different browser for each.

Set a Passcode On All Of Your Devices

Your phone, tablet, and laptop all contain sensitive information, and they provide access to your bank accounts, credit cards, and other financial tools. If one of them is lost or stolen, whoever gets hold of it can do a lot of damage in a short amount of time.

That’s why it’s important to set a secure passcode for all of your devices, so that if it leaves your control, it can’t be used by anyone else. You can set a passcode on your iPhone or iPad , or your Windows or Android devices.

If your device is stolen, you should remotely wipe it if it is supported on your iOS or Android device.

If Someone Asks For Something Out Of The Usual, Check In With Them

Impersonation scams—where a scammer impersonates your friend, family member, or colleague to get you to send them money or information—are becoming increasingly common. Scammers can even use AI tools to impersonate voices, so if someone texts, emails, or even calls you with an unusual request for money or information (which could be used for later scams), find another way to contact that person to confirm that it’s actually them asking.

The best way to do this is to contact them via another communication method. If you receive a suspicious email from a known address, give that person a call directly to confirm that they’ve asked. If you receive an odd phone call claiming to be from someone you know, hang up and drop them a WhatsApp to check if they made the call before calling them back.

Don’t Download Strange Software or Attachments, and never Run Macros

Viruses masquerading as legitimate downloads are everywhere on the Internet, just waiting for someone to click on them. Avoid unknown sources of apps and stick to Apple, Android, and Windows App stores whenever you can.

If you receive an email with a strange or unexpected attachment, don’t open it, and confirm that the sender is trusted and intentionally sent the attachment. And, under no circumstances should you run macros from a Microsoft Office document emailed to you: They’re almost never something people use outside of work, and if you’re at work, your IT department should manage which macros are trusted.

Use Antivirus and Stay Up-To-Date

Installing a good antivirus package is a proactive measure that you can take to help prevent malware from getting onto your devices. Windows Defender is a good, free, default option that ships with Windows 10 and 11. Commercial antivirus suites offer additional functionality like VPNs for extra protection.

Learn How to use Windows and Your Other Software And Devices

Your life will be easier if you know how to use your phone, tablet, and laptop properly. It might take a bit of a time investment, but it’ll pay off: you’ll be able to do things faster, make less mistakes, and you’ll know when something isn’t working properly. When you can tell that something isn’t quite working as it should, you can investigate by running a virus scan, or seek expert help to resolve the problem.

Don’t Panic!

If something isn’t working as expected on your device, stay calm. Don’t start mashing buttons or swiping all over the place, as you’ll only lose track of where you are or make things worse. By randomly tapping on alerts and notifications in frustration, you could grant a virus access to something accidentally (for example, by allowing one of the UAC prompts discussed above).

If you’re really having trouble, contact your IT department (or your nephew, or your tech-obsessed friend), and have them help walk you through fixing the problem. If you need to attempt a fix yourself, our tips on cybersecurity , and computer security best practices are a great place to start.
