I got the most recent ESET Cyber Security Beta for Mac. It offers a mode called “Web Protection” and “Email Protection”.

The documentation don’t really explain what these two modes does, and I’m curious about the potential privacy implications. In a Web browser, the domain name of the sites you are visiting are sent securely to the browser vendor and checked against a list to form what browsers call “fraud/malware protection”. In effect, this means that what you do online is shared with a third party. Is the same happening when using ESET’s functionality?

ESET Consumer Support have, unfortunately, been unwilling to answer questions about what the feature does and how it works.

They are both passive features. In either case when it detects a file it will scan it, before the file is created on the disk, in theory preventing the malicious file from ever existing on your drive. This is at least how it works on the Windows side. In the case of the Outlook plugin it will scan the file atachements, and in the case of the "Web Protection" it scans files as you download the file, all detection is passive without user ction.

@Daniel - I have used ESET for 2 years. This is my personal experience. I never claimed it was anything but personal experience. –  Ramhound May 15 '12 at 12:19
