1. 4/5Internet problems after app

   so I love this app it really helped my phone because I clicked on a wrong link and it said I had multiple viruses in my phone so my mom told me to get this app on my phone because I used to have it in and it confirmed that I have no viruses and it helped me secure my phone but now I have the Internet VPN on my phone and it makes my Internet so much slower and it is not good because I also have avast on my laptop, which I do my school on because I am homeschooled and it makes it both of my devices internets very slow, which won’t work. my mom also has avast on all her devices and she works from home so avast if you can, please fix this Internet problem, me and my family will be able to continue using your app to secure our devices but if we don’t start seeing change we will have to find a different app as our Internet is not working any more.

2. 5/5Slow Customer Support

   I’m a new user of Avast Security and, so far, I’m very pleased with the service. But… I have run into a couple of problems while using the iOS app on my iPhone. I haven’t been able to verify my email address. For some strange reason, although my email address is listed correctly in the Manage Account section, but whenever I enter it on the Data Breach Monitoring page to turn on that feature, the app automatically changes my email address by inserting three extra characters in front of it. I sent an email to the Avast support team from within the app (which the app indicated had, indeed, been sent). But that was a few days ago, and I still haven’t heard anything from them. I also tried to turn on 2-step verification in the app. I went to Account Settings, and clicked on the “Turn on 2-step verification” link under the Security heading. When I did that, a white screen popped open with a message that simply read “Please verify it’s you to turn on 2-step verification.” The problem is, after trying to scroll down to find the option to verify my identity, I didn’t find one. The white screen only had the aforementioned message and a small x in the upper right corner to close the screen. When I closed that screen, I was back on the Account Settings screen and was again shown the same “Turn on 2-step verification” link under the Security section. That screen hadn’t changed. It still didn’t give me the option to verify my identity. So I sent a message to the Avast support team about this new problem. And I’m still waiting to hear something from them…

3. 4/5Seems to work, but takes some juice

   Installed this app after I was finally fed up with all the scams and phishing nowadays. It definitely boosts my confidence in my overall security. I would like to upgrade to the paid service however, I have noticed that my battery life has gone downhill significantly since downloading and the battery health setting shows that in one day 50% of my battery usage is coming from this app all in the background. That’s crazy. To top it off I went through about 150% battery today as I am traveling. So on any given normal day. Just unplugging my phone for 16 hours and it will drop to 25%. That’s bonkers. I hope this issue gets resolved. I can’t justify giving money away for a premium service that will only cost me more down the road by having to replace my battery.

4. 5/5Excellent but small internet speed problem

   I’ve been using Avast free and paid versions for over 20 years on multiple devices like all my phones IPhones and Androids plus every single laptop and computer I’ve ever owned. I used to use Norton because always came pre-installed on every computer it is well known BUT is very expensive especially when you have Dad devices, mom devices and multiple kid’s devices and could be in hundreds that quickly. It is an huge file and it slows the device down DRAMATICALLY so much you don’t even want to use the device so I started researching for something different and that didn’t slow down the devices and came upon Avast and been in love ever since. The “Free” version is very good (as long as you do weekly or daily scans. You notice the device speed difference immediately when compared to Norton (ANY ONE OF VERSIONS). I was an network administrator college student and always recommended this software because of the security, ease of use and the price! Free 99 is very affordable and appealing to a college student on a ramen noodle budget lol. Ultimately this and other Avast products are EXCELLENT!! Always choose Avast over other “Free” apps because you’ll have strong protections without the big bill. 😊 Best Fre/Paid App in apple or Google store!!!

5. 4/5Pretty good

   I like it because I can use it on my iPad, but it does have some limitations. A lot of things it said in the description was actually for the upgrade version, and some features don’t work. For instance, it checks your email for data breach, but it keeps on prompting you to use it over and over until you upgrade. This can be super annoying. For users that don’t mind it, you would like this antivirus. Also, it puts on this annoying VPN, and once it is on, you can’t turn it off in the app or in the settings app on iOS. Every time you go to iOS settings and hit the button to disable VPN, it automatically switches it back on again one second after you turn it off. But it is a nice antivirus. The VPN can just affect certain sites like Disney+, but that isn’t too bad, as iOS has a Disney+ app anyway. These are my opinions about Avast Security. (Mac users can download the antivirus on their website, and that is the best antivirus ever in my opinion)
