I downloaded the MS04-011 and the worm removal tool from Microsoft.com. I launched my windows XP, and the removal tool worked successfully. But whenever I run the MS04-011 the first screen of the update application appears for a split second and then disappears. Then I noticed that all the small applications on my PC are corrupted in the same way, you run it, and it immediately closes by itself. How can I prevent the worm (or actually the code executed on my PC through the worm) from closing my applications so that I can install the update?
