I've been an Avast Antivirus Premium customer for years, I find it a great antivirus for my phone, and feel safe online and using my apps, it's a great service and great support as well, I highly recommend Avast Antivirus Premium.

Annoying, invasive, and KILLS battery life. What's the point in this app? Pure spyware, who knows where my data goes?? Absolutely destroys battery life. Even just idle with no special battery permissions, just running = terrible battery life. Handy features disappear. The app alerts / begs you to turn every permission / feature on. You can't enable the things you want like other apps. Conclusion, the app isn't simple to use. It's annoying an inconvenient and does who know with my usage info??

I’m very disappointed with the slow response from the support team. I have already sent two emails regarding the extra charges and the missing bill (where actually I don't subscribe for any product), but I have not received any follow-up or resolution so far. If the support team sees this review, please respond to my emails as soon as possible.
