I was hit by this worm two times yesterday
After doing a clean install of windows after a format, I came to BetaOne for testing my internet connection. When I was reading about this worm, the window appears saying my PC will shutdown
I restart and have just the time to download the removal tool from Symantec and my PC shutdown again. I turn off my PC, clean with the removal tool and install an antivirus (NOD) + ZA and after that, I was ok
