It was definitely not a Phising email I have had some of these before and sent them to PayPal, this was a cosher charge on my PayPal account as I logged onto my account to check, I also had my bank check it out and if I had not alerted them the charge would have been debited from my credit card account on the 29th of this month.I don't think that you have been hacked. Lots of users have been receiving scam phishing e-mails:
Phishing - Wikipedia, the free encyclopedia
that say that they have been charged on their PayPal account, on their UPS account, on their Chase credit card account, etc.
DON'T EVER click on anything in one of these e-mails. I hope that you didn't "lodge your dispute" with PayPal by clicking on a link in the e-mail you received. That's how they fool you into giving them sensitive private information.
You can use this free product to do a scan to see if you have an infection. But I'd be willing to bet that you don't have one. Rather, you fell for a social engineering trick.
