Clean Master Antivirus Review 2020

Clean Master Antivirus is one of the foremost popular junk-cleaning and system optimization tools for Android, featuring everything from social media app notification control to a fanatical WhatsApp scrubber. Despite 43 million reviews on the Google Play Store—most of which are positive— the jury is extremely much out on whether optimization apps like CleanMaster help or harm system performance. Although cleanup tools can release valuable space, they will also drain battery life and impede system performance. to ascertain if CleanMaster is useful, I dug through its extensive set of features to get the reality behind the hype.

CleanMaster does contain an antivirus tool that may be launched by clicking on the antivirus button on the house screen. The program runs a “Safety Scanning” utility in but ten seconds. Although I used to be ready to see what the scan was doing (“checking for malicious apps” and “checking for vulnerabilities” flashed on my screen), I didn’t get any quite report on which directories and apps had been investigated. I used to be also unable to vary the sort of scan.

The antivirus impressed a touch more with its reminders about required updates. The update frequency is often set to daily, every three days, or every five days, and therefore the program displays the version the app is currently using.

So how effective is that the antivirus component? Without much within the way of logs, it’s difficult to understand. However, CleanMaster has previously received the distinguished Best Android Antivirus Product award. I installed the “Test Virus” application from Itus Mobile Security, which installs the EICAR test virus. CleanMaster flagged the test piece of malware within seconds, although it didn’t warn about some things I had deliberately installed by enabling unknown sources within the security settings. Although this isn’t what many power users would like, it automatically scans newly installed apps and is quick to flag any potential sources of danger.

CleanMaster is far quite just an antivirus tool, however. Most of its functionalities fall into the “system optimization” header. Here are a number of its standout features.

CleanMaster’s junk file cleaner is meant to release the maximum amount of space on your device as is safe. The tool needs permission to look at and delete system files, but CleanMaster does an exceptionally thorough job at finding files and folders which will be deleted. On my first run, the program identified 3.45 GB of files that it thought I could live without—potentially a huge disk capacity saving.

Thankfully, unlike the antivirus program, the junk file cleaner provides ample detail on what files it’s flagged for removal. Within the system cache category, as an example, I used to be ready to view the disposable cache size by each installed app and even chose to wash them one by one. This provides great flexibility for users who could also be concerned with removing important settings information, like WhatsApp configuration files.

In addition to cache junk, CleanMaster also does a superb job at detecting and removing residual junk files. These are settings and configuration files that previously installed programs left behind even after uninstalling them. I do tons of app testing on my main Android device so wasn’t surprised to ascertain that a variety of these—including 360 Security—had left files in their wake.

The majority of the junk files were what it called “obsolete APK files.” Android Package Kits (APKs) are wont to distribute and install Android programs, like .exe installers in Windows. While APKs lying around a filing system might be unofficial package installers that the user forgot to delete, in my case these were files that my backup and restore app had intentionally created. Thankfully, I noticed this in time and chose to not delete them.

In addition to the essential junk files scanner, there’s a strong junk scanner that promises to flag even more files for removal. this needs enabling access for CleanMaster but didn’t add any time to the junk scanning process. Using the powerful scanner it found a further 500MB of files for removal. This included the system memories of some apps I exploit for transport and call management. I appreciated the very fact that it had been possible to click into each program and add it to an “ignore list” so that it might not be removed if I hit the “clean junk” button.

Phone Boost Attempts to enhance Operating State
In addition to removing files that are not any longer required, CleanMaster provides users with the choice to spice up the present operating state of the phone by closing unnecessary processes running within the background.

Smartphone users are familiar with clicking through many apps but often forget to shut them when finished. A result is often an outsized number of processes running within the background and dramatically hamper device performance.

Phone Boost Attempts to enhance Operating State
I was surprised to find out that I used to be running 36 apps during the testing process—only a fraction of them was visible to me by using the appliance selector hardware button on my handset. Among those taking over substantial amounts of memory were the transport app I hadn’t used since the morning, Google Maps, and a variety of secure end-to-end communication tools, including Signal and Biocoded, which require to be constantly running to receive calls.

The system attempted to automatically uncheck those applications that it thought shouldn’t be forced out of the background. While it did make some accurate guesses (including deselecting the Twilight blue diffusing screen which must run continuously), it got others wrong. Among those the system wanted to automatically close were my smart home control app, Pushbullet, AirDroid, a dual SIM control tool, the communications tools, and FolderSync Pro—a tool I exploit for automatically syncing local folders with my cloud storage.

The results of forcing of these apps out of the background could are pretty calamitous—important file transfer wouldn’t have taken place, my air conditioning wouldn’t have turned on, calls could are missed, and that I wouldn’t have received any PushBullet notifications which I frequently send from my desktop. If you’re getting to use a junk cleaner, manually inspect all proposed changes and don’t delete essential files or close required background processes.

CPU Cooler Prevents Overheating
Keeping too many apps or background processes open can put a strain on a smartphone’s CPU and end in overheating. This, in turn, can significantly shorten the lifespan of the CPU, degrade lithium-ion batteries, and—in extreme cases—render the device inoperable.

Android contains some built-in features to stop this, including throttling back voltage and resources if it detects the CPU is overheating, but CleanMaster makes the method more transparent for the user. a visible thermometer icon displays whether the CPU temperature is within normal limits(in which case the thermometer is about against a blue background) or overheating (in which case it’s set against red and notifications are triggered).

Although the feature is intuitive and nicely designed, I couldn’t see a difference between the app’s proposed cool-down strategy (closing down running apps) and what the system suggested to try to within the phone boost menu. Given the very fact that the phone boost tool also outputs the CPU temperature, I tend to think that there’s an enormous overlap between these two features.

Flag Abnormal RAM Usage
Granting access exposes another optimization tool: detecting abnormal RAM usage. This monitor triggers when an app is using quite a particular level of RAM, which might hamper resources and will be indicative of malware. This alert didn’t trigger during my evaluation, but if it works as stated, it might be a pleasant performance booster and how to avoid viruses.

WhatsApp Cleaner Frees Space Without Erasing Personal Memories
Over one billion people use WhatsApp a day and CleanMaster deemed it deserves its cleanup utility within the app. The WhatsApp cleaner flags content within the WhatsApp memory consistent with filetype. I used to be ready to review images, video messages (which were occupying 340MB of space), and voice messages and even inspect the files within each category. I appreciated that the WhatsApp Cleaner tool provided such a transparent breakdown before deleting things which may be special.

Other Utilities
CleanMaster also includes an SD card scanner. These cards are often loaded with viruses or rootkits from desktop devices, so it’s excellent that CleanMaster included a fanatical tool for this.
A message security tool protects user privacy by hiding the contents of messages from messaging service notifications, like Facebook Messenger and WhatsApp. this is often a pleasant feature but duplicates tons of functionality found within the stock notification management tools.
The CM AppLock tool scans your systems for apps that you simply want to secure with a PIN code or unlock pattern. this will be utilized in tandem together with your device’s primary security settings or independently of it. Either way, it provides users with the reassurance that albeit they leave their locked device exposed, critical programs containing potentially sensitive information can still be locked down.
