Online Crash Analysis is now capable of detecting some Internet worms and viruses. This error report was generated right after Internet Explorer became unresponsive and was closed by the user. OCA page shows that the application error was likely caused by Small.M worm and it is right. After doing a full scan in Windows Live Safety Center (http://safety.live.com) you can see that the computer has been infected.
