Ken,
I have read numerous horror stories about PayPal. It is not only not secure, they will say "it's all on you" if you are defrauded.
Stick with credit cards which cannot hold you responsible for theft/fraud provided you deny the charge within "x" days of discovering it.
I'd call you credit card issuer; it may be possible to dispute any charges made against your account this way. PayPal will do nothing for you.
