I mainly use this to lock apps, BUT it is getting to the point that it informs me that App Lock is not enabled on a weekly frequency. if any one stole my phone it would be a matter of days before App Lock was disabled, it's getting pointless to have this app at all. Previous review - I think I turned this feature off. Too much bloat, which I find annoying, such as clearing the clipboard, just clear it we don't need the stupid time wasting graphic, it should be instant.

Hey Ron, thanks for taking your time. The app lock feature certainly should not be automatically swithcing off after a week. If you feel it does, please reach out via the app's Menu → Help & support → Avast direct support, and let our support team assist you. Thanks, David*Avast

I wish the app would stop asking for a rating. That said, I've used Avast, exclusively, for my antivirus and maintenance needs for well over a decade. Not only has Avast unfailingly safeguarded my equipment, but the features available in the premium version have really helped to keep my hardware operating at like-new efficiency. Update, a couple years later: yup, still awesome.

This app is a scam! No different from your basic free app. I was told that I would get a 7 day warning before full subscription. Never got an email, nothing! Too many scare tactics to upgrade to premium. Too many ads. You can only reach them through email in 2 days and now they've taken my money and I can't even find my account on Google Play nor on the main website. My bank has already been contacted about these scam artist.
