These people ("NAME NOT FOUND" on Caller ID) called at 5:57 am! The person said he was calling to say that someone was downloading things onto my computer without my permission and to help me with avoiding that. Strong accent, but said last name was "Smith." Yeah, right!
Ridiculous!
We are already on the National "Do Not Call" List, but some of these people do not care. Also, it could have been a "phishing" scam.
Be warned!
