Same type of call about my computer sending messages of virus attaching to my email. "Anthony" with Indian accent from IT department from Z Tech Solutions in Florida ( looked this up and it's a recruiting company from Texas - probably doesn't know scanners are using their name). Anthony claimed he was working on the Russian hacking into Yahoo accounts and that my computer had been breached. Block this number from your phone but first have some fun with them because they deserve it.
This ZDGDGEES SDFWSR calls us all the time. These people never say a word. Like I have read this caller must be automated randomly calls. What is their purpose unless they are searching for personal info at our address.
