I have been using avast for years. I have NEVER been dissatisfied with them and never had my computer or phone go down to a virus. **Since this review avast has gone downhill terribly. Everything is seperated into different apps that you have to pay different subscriptions for. I can't get it to stop notifying me of products I don't want, it just leaves the notification up there for me to buy more apps. Garbage nonsense barely even works. Do better.

Is there anything this system DOESN'T protect? The more I navigated through the app, the more I saw what it could do. And I have the free version! I loved Avast! on my PC. Seems to be too much of a memory hog on my Samsung Galaxy S III. Otherwise, would've given it a 5-star rating. Needs to be streamlined for phones to be less cumbersome on the other running apps. Slows them down too much. Update: It's 11 years since my last review. I'm now in my 2nd year on a paid subscription for my Motorola.

Worth it. The first time I downloaded it, It caught Virus on my phone that I didn't even know about. Yes, The ads of the free version are a little annoying, but it typically only gives you one or two during your basic run down. It's better than having no protection. Plus you can just purchase the no ads thing. It also continues to scan in the background to make sure they catch stuff that actively tries to mess stuff up. 100% Try it out. Been using it for a good minute now. Hasn't failed me once.

What do you mean my payment has failed, I pay for the year, & is not even due yet, (April). You try to stop the constant ads to upgrade to highest tier, but you can't, even with given instructions..Subtract one star.. Oh, yes AND the scheduled scans aren't working, you set them constantly, yet NO scan.. Avast is starting to prove they can't be trusted.. Not renewing, subtracting another star..😠

I like this app very much if you have the regular version. I made the mistake of signing up for one of the advertising promos when logging off one day. I signed up for the $1.99 per month monitoring a step down from the $2.99 a month. I paid the first month right then and the service started. Well the next month came and they charged me $19.99 and some fee that totaled $21 and some change. This was going to be my fee per month. I cancelled the next day and requested a refund. No refund.
