McAfee Mobile Security 

Nowadays, phones are like mini-computers because we spend lots of time browsing the internet and accessing online services on them. But just like traditional computers, they can be hacked and become infected with malware if you click on a dodgy link or open a malicious document. An excellent way to protect your mobile device from different online security risks is by downloading a smartphone-friendly antivirus solution like McAfee Mobile Security

Available to download on both Android and iOS devices, it offers a system security scanner that can detect whether your operating system is out-of-date, a secure Wi-Fi scanner that’ll identify any anomalies affecting your internet connection, a media vault to prevent unauthorized access to your photos and videos, anti-theft protection for when your phone is lost or stolen, the ability to back up your contacts, a built-in VPN, web browsing protection, and lots more. Something to bear in mind is that features vary based on the subscription you choose.


Most people have multiple online accounts in this day and age, whether it’s email, social media, streaming, shopping, or a different type of internet-based service. And to avoid needing to remember lots of different passwords, you might use the same login for each of your online accounts. However, doing so can make it easy for cybercriminals to hack into your accounts.

But with 1Password, you can quickly generate strong passwords for all your accounts, access them in a secure app, and automatically fill in your different login details so that you don’t need to enter them manually. What’s also nifty about 1Password is that you can use it for storing bank account information, driving licenses, passports, addresses, notes, and other sensitive information, instead of just online passwords. Other features include multiple vaults, tags and favorites for organizing your data, the ability to search for a specific piece of information via Spotlight, custom fields, end-to-end encryption, facial unlocking, and more.
