My phone says that an android launcher update is required with information from get.mirando.de and that another page it toggles to say that an embedded page at www. mobile.xyz says that a virus has been detected and to press ok for an application to remove the virus. It will not let me do anything else or even shut off the phone. Please advise. Verizon tech support not accepting calls on the holiday weekend. Thanks!
Sounds like you have a questionable app installed. I would recommend you uninstall any recent apps you installed before this is happening to see which is the offending app, even up to maybe a month before as some of these apps can be "sleepers".
