The HOSTS file is a file on your computer that resolves DNS names to IP addresses, so it looks like the malware finished its job. It was DNS before there was DNS! This particular malware must have tampered with Jan's HOSTS file, disabling her computer from accessing certain Web sites like Windows Update. It would be wise to find the HOSTS file on her computer and find out if any other Web sites have been affected by this hack.

Incorrect Answers:

While the NIC driver COULD become corrupt from malware, the fact that she can connect to other Web sites suggests that isn't the case.

If the Web browser's cache was full, then she would be out of hard drive space. She would be having a different conversation with you at that point.

While there is a definite chance that malware might still be residing on the computer, it looks like another technician successfully removed all of it. We are just dealing with the after-effects of this malware. I would run another scan on the computer after I've made sure the HOSTS file was OK just to be safe!

Last Known Good Configuration holds all the critical information from the last successful boot. If Mike tries this FIRST, there's a good chance the system will return to its exact state before he installed the DVD drive. If he already rebooted successfully and THEN has the BSOD, the Last Known Good Configuration would not be useful.

Incorrect Answers:

Safe Mode loads generic drivers for mouse, keyboard, mass storage, and system services. Since the issue occurred before Windows fully rebooted, switching to Safe Mode would have little impact.

The Recovery Console is a command-line utility and is best at fixing the MBR, reinstalling the boot files and rebuilding BOOT.ini. The issue occurred after installing a new DVD drive. As a result, using the Recovery Console would not be the most likely solution.

Repair Install is a function of Windows installations and has nothing to do with installing DVD drives.
