The app is marvelous. Thank you! I just wish there was an app that would get rid of downloaded apps that cannot be uninstalled. dfndr does this! I was tooling around in the app and found an area that said get rid of apps you don't want. I checked it out and doggoned, this one app disappeared right before my eyes! Oh my gosh thank you thank you!

My girlfriend is the one that told me about this app. All she had was one of those free and INCREDIBLY SLOW AND CRAPPY government phones. It worked for her phone so well that I decided to use it on the last 3 phones I have had which were all name brand and somewhat fast that I actually spent money on! This app is awesome!!!

4 reasons why you need an antivirus app on your phone

The dfndr lab team shares facts about antivirus software.

 


REMOVE MALWARE IN REAL TIME

If you accidentally open a malicious file, hackers can quickly take control of your phone or use spyware to access personal information. A good antivirus app can prevent malware from being activated and installing on your phone by blocking it as it’s downloading.

 

 


VIRUS SCANS STOP INFECTIONS

Regular virus scans is a proactive way to keep your phone safe from malware, just like regular doctor’s visits can keep you healthy.

 

 


YOUR INTERNET CONNECTION MAY NOT BE SAFE

Hackers often target network connections that are free and don’t require a password. Doing a security check for any Wi-Fi network you connect to ensures your phone data isn’t exposed to vulnerabilities.

 

 


YOUR PERSONAL IS PROTECTED WITH ANTIVIRUS SOFTWARE

By installing the proper barriers with antivirus software, you prevent hackers from gaining access to your passwords, personal photos, videos, and other sensitive data.
