These 21 apps were found infected with HiddenAds malware that can serve up intrusive ads outside the app. HIGHLIGHTS 21 Android apps with HiddenAds malware were found by Avast Google has removed most of these infected apps.The infected apps have been downloaded around eight million times.  A set of 21 android apps infected with malware has been discovered by Czech antivirus maker Avast.  The apps are said to have been downloaded around eight million times. The security firm claims that the affected apps have adware, called HiddenAds, that disguises itself in fun or useful applications, but actually exist to serve up intrusive ads outside the app.  The malware, first discovered in 2019, can also hide the app icon – making it difficult for users to uninstall them, and hide behind relevant-looking advertisements, making them hard to identify, added the report. Google has removed most of these apps from the Play Store, but if you have downloaded them, ...

Max Planck Max Karl Ernst Ludwig Planck, ForMemRS was a German theoretical physicist whose discovery of energy quanta won him the Nobel Prize in Physics in 1918. Isaac Newton Sir Isaac Newton PRS was an English mathematician, physicist, astronomer, theologian, and author who is widely recognised as one of the most influential scientists of all time and as a key figure in the scientific revolution. Edwin Schrodinger  Erwin Rudolf Josef Alexander Schrödinger (12 August 1887 – 4 January 1961) was an Austrian physicist, one of the originators of quantum hypothesis(theory), and champ of the 1933 Nobel Prize in (Physics)Material science. His ideas were heavily influenced by monist philosophy and he is particularly well known for original interpretations of the significance of the wave function and for devising the Schrödinger's cat thought experiment. Ernest Rutherford Ernest Rutherford, first Noble Rutherford of Nelson, OM, FRS, HonFRSE was a New Zealand–conceived English physicist who ...
