Micro Guard™ Android ProtectStar™ makes sure that no hacker or spy can listen on you. With just one single click, the integrated microphone of your Android™ device will be completely protected.
Prevent spying
Not only millions of users, but also former FBI-chief tape over the webcam and microphones of their devices.
With good reason: Everything and everybody is spied on! We know this since June 2013 when whistle-blower Snowden revealed the first NSA documents. Since then, increasingly threatening details are being constantly uncovered. But not only have hackers found solutions to misuse the integrated microphones of mobile devices without a warning signal to the user: Also, spyware is highly dangerous because it specifically targets control of the built-in microphone to listen to the users.
Hear nothing – For those who should not
With only one click, the protection is activated, and Micro Guard™ blocks and observes all programs and processes that try to access the microphone of your smartphone. Every attempted security breach will be reported with a signal.
While all accesses and warnings are protocolled in the log file, the intelligent Deep Detective™ detects even previously unknown attacks.
Deep Detective™: A smart invention against (un)known threats
With the Deep Detective™, we have created an intelligent and versatile detective that observes all accesses to the Android™ device – similar to a firewall – only smarter.
Deep Detective™ permanently controls which process or app currently attempts to access the microphone. Additionally, it reports known – and thanks to modern heuristic methods – also unknown attack attempts.
Every possibility to spy on you is proactively restricted from hackers and spies. Checks microphone permission, protect microphone, restricts backdoor surveillance makes this a must-have spyware detector with incredible detector features.
With thousands of attack signatures, the optional Deep Detective™ Live spyware scanner detects a variety of fraudulent elements such as HiddenAds, FakeApps, Adware, LeadBolt, Sms-Thief, Rooting, Sms-Fraud, Fake Installer, Exploits, BankBots, Anubis, AgentSmith, SMSReg, FinSpy, Ransomware, LokiBot, Banker, Sms Sender, AirPush, etc.
Block microphone, protect recording, disable the microphone, and defend yourself against microphone misuse. One of the top-rated microphone apps around that can disable the microphone for unwanted surveillance. Disable mic and do much more with this microphone application.
An ideal combination
Micro Guard™ can, especially with activated Deep Detective™, be used ideally in combination with other existing security solutions. And it works perfectly together with Camera Guard™ that protects the integrated camera of your device. The microphone blocker that you can trust.
