Sasser is a worm that spreads itself via the Internet. An unprotected Windows XP machine will get Sasser within just a few minutes of being put on the ‘net. I just recently saw this video clip by the BBC that demonstrates a computer under attack by the sasser worm. It’s not clear how long the clip will be available, but it’s worth viewing. To protect your system run Windows Update regularly and use a firewall (a broadband router will do fine).
To remove the Sasser infection follow these steps:
shutdown -a then press OK. That will stop the worm.
