这是冒充 McAfee 的骗子吗？发这么个账单接下来怎么骗的？等我打电话上钩？

bing 了一下，果然是骗子：McAfee Invoice Scam is a malicious email that pretends to be from McAfee, a computer security software company. It claims that the recipient is being charged for anti-virus software and asks them to call a phone number to cancel the order. However, the phone number is a scam call center that tries to trick the victim into giving personal or financial information. The email also contains a malware downloader that can infect the computer with various threats, such as ransomware, spyware, browser hijacker, and trojan virus. These threats can damage the system, steal data, encrypt files, lock the computer, and allow hackers to access the PC remotely. McAfee Invoice Scam can also modify the windows registry, generate malicious files, corrupt crucial sections, hijack the Host files, and block the Internet connection.
