I open my Automatic Updates to see what is going on with it, and I see several messages with hyper links. I open those and I am slammed with several ways (which I believe are all fabricated) that an attacker can take control of my rig. Here is one example:

General Information
Executive Summary
This security update resolves three privately reported vulnerabilities in Internet Explorer. The most severe vulnerability could allow remote code execution if a user opens a legitimate HyperText Markup Language (HTML) file that is located in the same directory as a specially crafted dynamic link library (DLL) file.

Did I just make a huge mistake by opening these?
EDIT: This site also tried to mimic Microsoft.

I Google'd to get info on this. There was no date on what I found so I don't know if it is recent or not.

If it is recent, there is a possibility that you have a trojan named dnetc.exe on your PC. You might wanna run a few scans with your anti-virus program.

Good luck!

Download and install Microsoft Security Essentials and scan. If it comes up with nothing, your fine.
