Which Antivirus is Better?

Which Antivirus is Better?

Both ESET and Bitdefender are rated at the top of antiviruses thanks to their innovative combination of signature and heuristic scanning—the first method identifies viruses by their known features, while the second looks for suspicious behaviors that could signal a new infection. However, this is where the similarities end.

Bitdenfender focuses on offering comprehensive security for a whole range of cyberthreats. They use a Safe File Vault to protect your important documents from ransomware, and a virtual keyboard so your passwords can’t be intercepted by keyloggers. The Webcam Protection keeps your video streams private and the SafePay browser protects your card details during online purchases. Bitdefender is available on all major operating systems, but the only downside is that it uses significant processing power which can slow down your computer.

ESET doesn’t include as wide a range of extra features. Instead, it focuses on making the antivirus as discreet as possible. The Idle Scan mode waits until your computer is asleep before scanning so it won’t interfere with your online activity. Gamer Mode blocks pop-up notifications during full-screen gameplay. ESET’s near-100% protection scans all files during download, so infections should never actually reach your device.

If you’re not using Windows and you’re looking for protection from a broad spectrum of threats, then Bitdefender is the clear winner. However, if you use your computer for processing-heavy activities, ESET has the least impact on computer speed and will be the better option.
Time To Decide Which One Is Best For You

Frequently Asked Questions

How do I find the best antivirus for me?

The first thing to do is to understand what you need — all antiviruses come with different internet security tools to help you stay protected, so identifying what level of protection you want will help you figure out which product is right for you.

Some antiviruses have a virtual private network (VPN), some have safe browsing extensions, and some have a password manager. Some only work on certain operating systems, while others cover all operating systems across multiple devices.

It’s important to compare the best antiviruses on the market to find the perfect one with the functionality you need.

What makes an antivirus secure?

It will also offer real-time protection against all threats, regardless of whether you are browsing the internet, downloading software, shopping online, or opening email.
