Which Antivirus is Better?

A top antivirus needs to be secure and forward-thinking. Bitdefender and Avira meet these criteria in different ways. They use a combination of signature and behavioral scanning to identify all kinds of malware, as well as helpful additional features to protect from other attacks.

Bitdefender’s Safe File Vault keeps your important documents secure from ransomware attacks. The Webcam Shield protects your video stream from hackers, and a virtual keyboard and password manager keep your passcodes safe when logging in. Bitdefender also performs hardware scans of USBs and external hard drives, so you can’t transfer infections between devices. The antivirus is available on all major operating systems, which is a definite bonus. The main downside is that the app uses significant processing power; some users have claimed it slows down their machines.

Avira is only currently available on Windows but still provides useful features. There are anti-ransomware and anti-phishing protocols and it helps to optimize your Windows Firewall. You also get payment protection and a very handy price comparison tool. Avira doesn’t cause system slowdown since the PC tune-up tool speeds things up by deleting duplicate, out-of-date, or temporary file logs. The company also offers a ”Virus Lab” to keep you updated on the latest threats.

While Bitdefender provides a more extensive range of additional features, it can cause system slowdown. If you don’t regularly undertake data-heavy tasks, that shouldn’t matter. However, if you use your device to stream, edit photos and videos, or play online games, then Avira’s lightweight antivirus software may be the better option.
