Avast Mobile Security & Antivirus in detail

Antivirus Engine: Virus and malware scanner automatically scans for infected/dangerous apps and Trojans upon first use. Includes Web & file scanning for complete mobile protection, and also protects against spyware and viruses.
Junk Cleaner: Instantly cleans up unnecessary data, junk files, system caches, gallery thumbnails, installation files, and residual files.
Call Blocker: Keep your privacy. Add phone numbers to your blacklist and block callers you don’t want contacting you.
Web Shield: Scans and blocks malware-infected links, as well as trojans, adware, and spyware (for privacy and safe Web browsing, e.g. Chrome) and also fixes mistyped URLs.
Wi-fi Security: Check the security of each network and email, browse and make payments wherever you are.
Photo Vault: allows you to protect access to your photos with a PIN code. After moving photos to the Vault, they are encrypted and hidden.
Power Save: reduces your device's battery consumption by adjusting set of settings such as the Wi-Fi, synchronization, Bluetooth and screen settings that drain your battery the most.
