Good day all,
Please can anyone recommend to me  free and functional QRcode and Antivirus
installation links that can scan any QRcode and access the link
automatically.  Also, good antivirus with effective functionalities.
So many of them in Google play store but prefer anyone that people have
used and found very effective.
Thank you.
