A probable spammer, maybe more than one has gotten my address and is sending an increasing number of ads / SPAM from say Fat Burner [firstname.lastname@example.org] which I don't know how to find an address to block. All come from yahoo.com. I thought yahoo had some kind of program to block or eliminate these emails. He/she has my address so I am concerned and want to know to block his/her emails, protect my computer. Is there some way such as finding an IPO and then blocking that IPO? I know there a number of commercial programs, but don't know which ones you can trust.
I'ld like to learn if you could step me through a process, I would be very grateful. Thanks in advance
