1. 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!!!

2. 5/5Just what I needed!

   I’m grateful this product continues to be made available for free after all these years. Avast has always had a solid reputation, and their efforts to stay competitive are evident in their real-world protection rates against zero-day threats, thanks to next-generation AI and machine learning. I don’t yet have the capital to justify investing in a cold wallet (I do have an MPC wallet), so I use a dedicated iPhone with always-on VPN (in case of malicious actors grabbing the IP from a transaction to try a direct attack) for my wallet apps, and nothing else. While iOS prevents antivirus from being able to block files, it can still help by blocking access to malicious domains at the network level. I went to an unfamiliar DEX in Trust Wallet’s Web3 browser, and, sure enough, Avast blocked it. It also blocks malicious iFrames on legitimate sites, so I can visit them while still having protection against cross-site scripting. And it coexists perfectly with my VPN. Nothing is 100% immune to hacking, not even a cold wallet. But with the combined layers of iOS security, App Store vetting, IP masking, and Web filtering (as well as my use of unique and complex passwords, 2FA, and biometrics), I’m about as close as a hot wallet can possibly get.

3. 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…

4. 1/5Information not accurate- poor results comparing to other softwares that say otherwise

   I downloaded this app along with the other Avast apps as well as installed Avast software onto my laptop because research and reviews say this is a highly rated and reputable software to use. Although I have learned that is lot accurate. Based on other software I am using and comparing those to this company, the results from Avast are not 100% NOT accurate. According to the other softwares and my credit reports, my identity has been stolen and my information is being sold online and has been for quite sometime due to many different channels; breaches and phishing through my emails and browsing history. My computer and phone was hacked on 6/15 by a Trojan that was implanted on 3/18. Since then I have had some alarming signs whoever is behind it may still be in one of my emails I have monitored by this app. According to those other softwares, each has detected one or more of these compromising matters. This software, after each scan says my identity and information is not compromised or of a concern to be alarmed about or to look into further for resolution. Disappointing and now even more concerning because I gave my information to another company for a possibility for more information to be leaked.

5. 5/5Should I Even Have This App?

   Note: Before I start, I caution anyone using the app to click on the VPN and turn off auto-connect. It hasn’t asked me to allow auto-connection which proved to be suspicious on its own. It appears ever since I downloaded this app, strange things have been happening on my phone. Random gibberish being typed, and sent, when I’m not even laying a finger on my keyboard yet about to type to someone I know. Not to mention the “glitching,” as my phone jumps from up to down, the message being cut in half as it seemingly taps onto the middle of my text and adding letters, again when I’m not even typing. As well as multiple times throughout this message I’ve had to copy and paste as it keeps messing with my message and cutting off it off entirely. My personal opinion? Delete this app if it’s giving you the same issues something shady is going on and it can cost you. I can’t type anymore with it, it’s purposely messing me up. For all I know this app could have been corrupted or who knows what. What I do know is that this app is not all that it seems, maybe it even trying to gather all my data. I got this app because I found out on pc that it was available on phone, so I got it. Seems like it wasn’t the best action to take as something like this has never happened to me, that is, of course, until I downloaded this app on my phone. As for why I have it at five stars? Not because I like it, in fact this experience has made me become distrustful of Avast, especially on phones and tablets. I did it so that whoever has this app knows, or I guess doesn’t know but will now, what the possible dangers could be with it installed.
