I have recently discovered that my HP is infected with Sirefef... I am running Windows 7. MSE was disabled and once able to scan found the infected files. Unfortunately my computer displays an an error after loading the desktop stating that there is an issue and the computer will restart within 1 minute. I was able to get a partial screenshot of the error prior to the shutdown. While, I didn't have enough time to position it to show all of the files, it does confirm that Sirefef is responsible. Regardless of if I boot my computer in safe mode, or even not log into an account the system restarts within 2-3 minutes. I'm headed off to bed tonight as I am tired of dealing with it right now, however look forward to working with you to get the problem resolved.
