scam attempt using anydesk app

I was contacted by a number that appeared as COMCAST in my Caller ID.  The caller said my modem was at low security and asked me to check for blinking lights when he sent a signal.  Then he walked me through steps to sign in to my account.  Next he asked me to download "ANYDESK" and download to my computer.  I told him I would not download anything then he hung up.

BEWARE!!!
