Just got the sixth call from this number. Decided to answer. Caller said he was with the Arizona FOP police organization.
Told him to stop calling. He politely said no problem and would take me off his calling list. Righttttt.
I got the standard call from "Internet Security" It's a scam where they claim your computer is infected and offer to help. If you take their bait and install their tool, they will encrypt all your files and demand a ransom to decrypt. Make backups of your important stuff :-)
