I tried to download a variety of infected files to my computer, and Bitdefender Shield blocked all of them before I could begin to do so. The full system scan took around an hour, but this wasn’t an issue as it was so lightweight it barely affected my system performance.īitdefender’s real-time protection, Bitdefender Shield, is also excellent. I tested Bitdefender by downloading hundreds of malware samples to my computer, including viruses, trojans, rootkits and ransomware. Most scanning happens in the cloud, so the scans only take up a tiny amount of your CPU.īitdefender detected 100% of the malware on my computer after a full system scan. It uses machine learning and a huge directory to detect malware. Similarly, if you’re cautious and go further and check TrustPilot reviews for a company, don’t assume they are all genuine.Bitdefender’s malware scanner is lightweight but powerful.

Even if you don’t read the comments, you may see a high rating from thousands of people and again assume it’s safe to download it. It’s worth being sceptical of user reviews, whether in an app store or on a website: it’s easy to post fake five-star reviews. Why would you install a fake app in the first place? It could be that it’s managed to get into an official app store and you assume that it’s legitimate. The other way you can be scammed is by paying a subscription for a service that isn’t provided.

If the app doesn’t scare you with notifications that your phone or computer is infected, it might just run quietly in the background and spy on you using the webcam and microphone and maybe even recording everything you type. And that is one way that they can get your money directly or, worse, get your payment information and access to all your money. Because the app is free, the warnings often demand payment to remove the (non-existent) virus and clean up your device.
