Paid them for a year and it can't even remove the malware on my phone. What a scam. Response: I already tried that. When your app didn't work I canceled my subscription. Even though I paid for the FULL YEAR it just removed the subscription entirely. Update 2: I can't reach out support is a subscription only feature. Which I no longer have despite paying for a full year. I want a refund. I can't believe canceling a subscription renewal removes what you paid for.

Hi, this issue will probably require some dialogue with our Support Team, which may be a difficult task here on Google Play. Can you please contact us on android@avast.com and describe your problem in detail? Thanks, David*Avast

High quality product. They have many features and great detection rates for the price. I went through all of the third party testings for different antivirus etc and it was either this or Bitdefender. This is slightly cheaper and has like a 1% higher detection rate than Bitdefender and I chose this. This product actually works not that others don't but for the features, security and price point this one was a winner for me. I would recc. Avast but if you don't choose them look at Bitdefender. (:

Doesn't appear to be a memory hog, and asks little of the consumer. Runs silently and simply behind scenes. My latest attempt to download the March upgrade just doesn't happen. After jumping thru all the hoops, nothing happens, yet play store indicates I'm due for an upgrade. THE UPGRADE WILL NOT DOWNLOAD on my Samsung Galaxy 5 ‐-------- 8 years ago I left a review. All is well. Avast works like a charm
