Yesteday was a bad day. I wasted several hours cleaning up after W32.Blaster.Worm. Now I vent…

I always install all of the Windows XP patches available on the Microsoft Windows Update site. A few weeks back, however, my computer started behaving strangely. Every other time I booted, it would show the Windows XP splash screen and then … zap … the screen went black and the PC shut down. Whenever I would restart, Windows XP gave me some menu saying the PC did not start correctly and I had the option of rolling back to the last known good configuration.

Not being a Windows expert, I did the following:

  • uninstalled a whole bunch of programs that I no longer use
  • ran Norton Utilities to check for registry problems
  • scanned the hard drive for errors
  • verified that all available patches have been installed
  • make sure the startup folder was empty

Blah, blah, blah…I could not eliminate the problem. So I eventually chose the option that let Windows revert back to the last known good configuration.

After choosing this option, my system came up in this horrible VGA mode and I had to re-install the device driver for my video card. After that, the bootup problem went away.

So my computer has worked perfectly for a few weeks, until I got this Worm/Virus thing.

My Theory

My theory is that when I told Windows to startup using the last known good configuration, it backed out my display drivers along with some or all of the Windows Updates. This is why my system was vulnerable to the virus.

The problem is, I don’t know WHICH patches are or are not installed now. When I view the installation history on the Windows Update site, it shows that I have installed every available patch. But that cannot be true, because the Worm only infects systems that do not have the appropriate patch.

Oh well. I’m not really looking for advice at this point. This is just one more little nudge pushing me closer to Macintosh for the next big computer purchase a year or two from now.
