Get a really good malware app. Ours catches as many as a dozen tries a day. They are as annoying as the dozens of "spoofed" scam calls on our land line. So far, the internet phone calls are less affected. Just DON'T give out your number unless you absolutely know who you are dealing with. After the FCC "do not call" try flopped, they are now tracking scam calls and matching the caller and the ID shown. If they don't match, very stiff fines follow.
