Even when you get a legitimate one, not many can completely remove viruses from your computer. That’s why I tested 30+ virus removal software and selected only the best 5 that can remove any virus and the broader spectrum of malware with 100% efficiency. Among the options, Norton is the best virus removal software thanks to its perfect removal rates, fast scan times, and a suite of extra features. You can try it risk-free with the 60-day money-back guarantee....

While a VPN can technically change your IP address to a different location, we do not condone this practice as it could be considered copyright infringement and violates Disney+’s terms of service. If you want to use a VPN for safe streaming, be aware that some may not work because Disney+ actively blocks VPN connections to protect its licensing agreements. My global team tested dozens of VPNs with their local Disney+ accounts and identified a few reliable options....

Last Updated: Aug 7, 2025 AdGuard delivers on its promise of protecting your privacy while browsing the web, but the VPN component isn’t quite up to par. Being in a secure location, having effective security measures in place, and enabling you to access some well-known streaming services on a variety of devices are all nice, but they don’t make up for the high price. If you’re considering signing up for AdGuard VPN, there’s no need to worry about committing to a long-term offer without trying it out first....

To save you from legal issues when traveling abroad, I researched the status of VPNs worldwide. I’ve compiled a list of countries where VPNs are restricted, but note that the laws concerning censorship and privacy can change at any time in these and other places. After testing over 30 leading services, I’ve concluded that ExpressVPN is the best VPN for restrictive countries as all its servers are obfuscated — it even works consistently in China....

I extensively tested both antiviruses and compared their results across 15 categories, including detection scores, system performance, useful extras, and value for money. I found that Avira leaped ahead of Avast in most categories, but it was still a close contest. Avira gave me near-perfect detection scores and real-time protection in repeated tests. Despite lacking a firewall, it kept me safe from all online threats. It also didn’t weigh down my PC and improved my system performance with its optimization tools....

While the firewalls I’ve picked are good for basic safety, you should note that a premium antivirus with a built-in firewall is a better choice. For instance, Norton has a highly secure and customizable firewall that works besides its other features to ensure airtight protection....

First published: Apr 23, 2020 Updated 2 times since publishing With no computer apps, Boomerang is exclusively for smartphones, and many of its features don’t work with iOS. I installed it on my son’s Android to evaluate and test all of the features. I challenged him to try and bypass the rules so I could see just how good it really is. Not only did most of the features not work very well, but the Boomerang app drained my son’s battery....
