Hello. Yesterday, my PayPal account was hacked. In a phone call to customer service, the agent at PayPal said that I'd fallen for a phishing email (very well designed and looked like all the emails PayPal sent me). The email sent me to PayPal login, which was real, and I signed in. The agent said the hack might have put a keylogger on my MBP. What software do I need to scan for this? It would be nice if it could detect other malware. I'm technically illiterate, so please answer accordingly, not leaving out pertinent details because "everybody knows that." I can assure you, I don't. Many thanks for your help. Here is all I know about my MBP.
