What is "com.apple.WebKit.Networking.xpc" doing in my Firewall options - allow incoming connections?

Regarding the site hotvirusmalwareremoval.com - the name itself made me suspicious, so I googled it and NEARLY ALL the hits were pages on the site itself. I could not find ANY third-party reviews of the site, its products or services; and there is nothing in any Wiki about it. This makes me very suspicious of the site.

In addition, if com.apple.WebKit.Networking.xpc is in fact an Apple/macOS component why is this site making extraordinary claims that it's "a dangerous computer infection which hijacks your internet browsers" and then offers steps to remove it?

I understand you probably can't answer that question, but the entire situation surrounding that site makes me very suspicious that it could be a scam and source of malware. There have been plenty of other rogue sites that claim to clean up your Mac, remove viruses, etc. that leave you off much worse than when you started ... Mac Cleaner/macPaw, anyone, for example?

So ... is it a legitimate/necessary part of Safari ... or is it malware?

(BTW, I have malwarebytes and when I scan it says my system is clean. I'll also run Etrecheck and see what it says.)

The file is located in /System/Library/Frameworks/WebKit.framework/Versions/A/XPCServices

Here is what GetInfo reported:

The permissions are:

system - Read & Write

wheel - Read Only

everyone - Read Only

ps. It appears to be an Apple product (unless it's possible to spoof information that GetInfo would report on a file).
