My colleague was surfing the net with my NEW android in my absence. I do not know what he surfed but when I clicked "back" in the browser ..It took me to a website called "cookmobiapps.xyz" and my mobile just started vibrating continuously with a message "your battery is infected with 2 viruses, hit OK to remove. DO NOT LEAVE WEBPAGE" Everything on the screen froze so I clicked OK, then a screen appeared asking me to download an app from googleplay (which I didnt). My phone works fine now and I have not tried hitting the back button again. Why did this happen? What was that message about? Its a new phone and Im very worried :'(

    No problems are there with your phone. It was the browser which caused that vibration and it did so because that popup/website told it to do so. Coupled with that scary message is what constitutes a typical phishing attempt on Android devices. Always ignore whatever they say or recommend, no matter what. Since they are inconvenient, switch to an ad blocker. Let us know when the issue is resolved. – Firelord Mar 5 '16 at 11:06
  • Thanks.. I installed 360 security, which detected a malware (that I removed).I deleted the history, cookies, cache, etc. But when I clicked the back button in the browser, the same website came with the same message. Again,the phone froze & clicking "OK" was the ONLY WAY TO GET THE VIBRATION TO STOP. Again it took me to the same page asking me to download the cleaning app.(which i ignored and deleted the malware again).I used HTC earlier, which allowed my to clear history from the browser AND an app manager. How do I stop that website "cookmobiapps.xyz" from appearing in my browser on Samsung? – user154667 Mar 5 '16 at 11:35
