Bitdefender is among the top antivirus programs available on the market. It can detect more malware threats and has a user-friendly interface, and better customer support options. It also scores higher in independent tests conducted by AV-Test and AV-comparatives.

In contrast to most antivirus software, Webroot SecureAnywhere is a cloud-based program that uses remote detection to protect devices. It works by scanning and comparing files with the cloud database. This method has minimal impact on the performance of your PC and can be used with older software or hardware. Its security features include real-time threat detection, ransomware security as well as phishing protection and firewall capabilities.

Webroot’s user interface is dark and may not be as sleek and modern as the other competitors, but it still is intuitive and easy to navigate. The main screen displays the status of your computer and lets you perform the Smart Scan, or a manual check. The left side rail contains all the major functions and utilities organized into four broad categories.

Avast’s interface is more modern and minimalist. The main screen is simple and displays the status of your PC and allows you to run a Smart Scan or manual check. The left side rail combines the most important functions and utilities into four broad categories, making it simple for beginners to use.

Both companies provide excellent technical support and documentation resources. Avast’s website is a searchable knowledge base, which includes helpful guides for different products. It also includes an email form to contact customer service representatives. It does not have live chat, as do many of its competitors.
