Upon renewal, thee software does not perform the same, and every time I opened the software I have to deal with an obnoxious ad for online casino gaming. I was not only forced to endure watching the ad but had to go thru GooglePlay to stop it. I notified Avast to cancel, which they did - as of 1/25/26 - but said NO REFUND DUE! As I couldn't use the program, & cancelled within 2 days of renewal, a full refund is reasonable. Therefore, given no choice, I have disputed these charges with my bank.

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.

I mean, really? Look, Avast: I know I have apps I rarely use in addition to apps I never use and need to delete. But, some of those rarely used apps I DO want to keep, even though I use them rarely. Why the heck would you ask me if I want to free up space by deleting apps WITHOUT ALLOWING ME TO PREVIEW WHICH APPS YOU'RE TRYING TO DELETE?! That's moronic. And you made it difficult to report easy-to-fix problems (like this). Lost you 3 stars.

I've only had Avast on my Android phone for a few weeks, but so far I'm impressed. It seems to provide a good level of protection without being heavy-handed or getting in the way. Note (7/31/2025): A couple of recent reviewers noted odd glitches. I've found that those who go for long periods without shutting down their phone, or at least doing a restart, tend to have such problems. Some time off and cache clearing are helpful for keeping smartphone glitches at bay.

App will not work for me (free trial version), after a scan it shows an add, I wait for it to finish, then shows add screen with the "X" (top left), I click the "X"...and it does nothing, stuck. Only way out is to hit back button, which I get a pop-up that if I continue to go back the scan will be cancled. This is unfortunate because I've heard this company has great customer service response which is a must in security yet strangely hard to find.

Horrible app. I had to leave at least one star and it's not even worth that. I had a pop up ad scam hit my phone and I subscribed and downloaded and when competed scanning it said I had no issues. Found out I fixed it through Play Protect. They also told me I would have 7 days and I canceled subscribing in 20 minutes and they kept my money anyway, going to credit card with complaint.
