How to heal ROM from trojan virus because I have to force stop Panasonic OWS version 1.0?
The best thing to do in such cases is to install an antivirus application. I highly recommend Malwarebytes or Bitdefender. They're both applications ready to be installed from the Play Store.
Once you install one or the other, initiate a scan and wait for it to finish. The trojan will be removed.
