This Caller called but wouldn't answer, and hungup. I checked on the internet the is listed under mary Jacobson or Paul Jacobson.
I don't these people so be suspisous of them.

I got a hang-up call from this Jacobson.  Have no idea who or why.  Beware.

Got a call from this number .. wanted to renew my Norton anti-virus (Haven't had in 3 years) ... Offered lifetime membership for just $70 ...
ID shows FtMcDowell .

I called the number back (call was to my cellphone, so I'm really not concerned). An answering machine said "mumble-mumble Jacobson mumble-mumble-mumble," so I hung up.

Received a phone call from this number on my landline a couple of days ago; the caller ID came up with AntiVirus Alert or something to that affect.  I did not answer the call, and I don't know anyone in AZ.  I will report the phone number to the DNC listing and FTC.
