I've been using this for quite a while, with few complaints. Mostly that when it "found" a problem, it would give a cryptic little message and insist that the identified problem app be removed. No information about what kind of threat, what kind of risk, no option to whitelist an app based on running alternate anti-malware apps and seeing no problem, and evaluating the nature of the threat and risk. Or perhaps the questionable app could be blocked, to see if updates to the app or the scanner definitions (of either V3 or the other scanners) made the "problem" go away. Two weeks ago, I got another hit. Re-scanned with other anti-malware, searched the web, found nothing. So I uninstalled. Then today, I decided to use some coronavirus lockdown time to take a harder look at alternate scanners. There used to be rumors that "security" software would throw the occasional false hit, to make users glad they had been "saved" from a problem, and keep paying the fees. Maybe this is one of those or maybe not. But in this case, the "malware" was only found by "cloud scan," not with "cloud scan" deselected. I have trouble believing that a real malware hazard couldn't be found by the updated internal scanner after two weeks, and couldn't be found by half a dozen top-rated scanners after two weeks.

I use to love this app for it's all in one approach. I could scan for malware, delete big files, and clean up RAM. I didn't enjoy the ads, but it was free so knew there was a trade off here. But then they removed the RAM cleaner?? My mobile phone doesn't have a ton of RAM and I needed it to make sure my phone didn't lag, and now it's just gone. Sadly it looks like I'll need to move on to another security suite.

Now that I have been using the free version of V3 Mobile Security for 6 months, I realize this is a keeper & ready to purchase a full version. It does not annoy me with popup ads, & scans upon my request, along with updating the app definitions. Other competitions are all too intrusive with all those marketing popups. Told my family & friends about this V3 from AhnLab.
