I have been receiving junk mail allegedly from PayPal for months. 

Finally started marking it initially just as 'junk' and later as 'Phishing Scam' which briefly stopped the problem. 

Now the same letters are arriving showing the sender as my own address (and not the only one that anyone would legitimately have on record).   I'm afraid to mark these as 'junk' as I occasionally send myself stuff from my own address and don't want to block se items I do wish to receive.

It does not appear that my account has been hacked again (as happened once before). 

What can I do to stop this harrassment and protect myself (I'm not very computer savy) from any risk from the "PenPal" site?   I should confirm that I have never used or contacted PayPal at any time.

HELP!
