Performance boosting capabilities
Antivirus giant Avast has produced another quality app which goes above and beyond being a mundane scanner, although that said, it does virus scanning very well, and is highly rated by the independent test labs.
Avast Mobile Security’s nifty features include an anti-theft system allowing you to track and remotely lock (or wipe) your Android device if it’s stolen, or if you lose it. There are also some interesting performance enhancing features including a junk cleaner to free up storage space, and a ‘RAM boost’ which aims to speed up your device.
The app used to be paid but is now free, albeit supported by ads. You can pay a small monthly or yearly premium to remove the adverts if they annoy you, though. Another very useful premium feature is ‘in-app locking’ whereby your device will ask for a PIN before opening certain apps. This prevents malware from launching apps such as internet banking automatically.
