Bitdefender is a top antivirus program. It has a more comfortable user interface and superior customer support. It also has higher scores in independent assessments carried out by AV Test and AV-Comparatives.

Unlike most antivirus software, Webroot SecureAnywhere is a cloud-based application that utilizes remote detection to safeguard devices. It works by scanning and comparing files to the cloud database. This method doesn't have a large impact on the performance of your PC which is why it can be used with older hardware and software. Its security features include ransomware security and protection against phishing.

Webroot's dark interface may not appear as sleek or modern as its competitors, but it's still logical and easy to navigate. The main screen displays the status of your PC and allows you to run a Smart Scan or manual check. The left side rail houses all the most important features and utilities that are grouped into four broad categories.

The interface for Avast is more contemporary and minimalist. The main screen is simple and shows the status of your PC and allows users to run a Smart Scan or manual check. The left-hand side rail categorizes all of the main utilities and functions into four broad categories, making it simple for new users to use.

Both companies offer great technical support and documentation resources. Avast's site has an interactive knowledge base that includes helpful guides for different products. It also has an email form to contact customer support agents. However, it doesn't provide live chat like other competitors.
