DuckDuckGo won't also stop viruses, and other malware from infecting your device. You still need to use a good antivirus software for that, and remember to always think before you click.
Can DuckDuckGo be trusted?
It is an open-sourced software and creates a safe and secure platform for the users. Having access to your data may result in a cyberattack. Almost all search engines don't have as strong security as DuckDuckGo. This platform ensures safe and private browsing on the web.
Does DuckDuckGo block malicious sites?
Like many other internet companies, DuckDuckGo's search engine protects users from malicious websites using a Content Security Policy (CSP).
