I want to scan my device for malware and protect it against phishing

AdGuard Ad Blocker, even equipped with powerful tools and features, is not a replacement for an antivirus program. And though it can’t scan your device for all sorts of nuisances, it will alert you when you visit suspicious websites — you just need to enable the Browsing security feature in the app’s Protection tab.

AdGuard checks URLs and domain names using hash prefixes, then our servers respond to the app’s query with a list of all possible addresses that match the hash prefix. When a potential threat is detected based on hash matches, access to that website is immediately blocked.
