Subject: MyDoom download info

February 12, The Register (UK) - Nachi variant wipes MyDoom from PCs. A
new
variant of the Nachi worm which attempts to cleanse computers infected by
MyDoom and download Microsoft security patches to unprotected computers
arrived on the Internet Thursday, February 12. Nachi.B (also called
Welchi)
uses the same security vulnerability exploited by the Blaster worm to
spread. Once it infects target machines the worm attempts to search and
destroy any traces of MyDoom infection -- before downloading patches for
the Microsoft vulnerability it used to infect the system in the first
place. The scanning traffic generated by the original Nachi worm in August
2003 caused huge problems. Anti-virus vendors fear a repeat performance
this time around. This concern is compounded by the plethora of new
viruses released in recent days. As well as the Doomjuice worms (which
target Microsoft's Website in DDoS attacks), we have MyDoom and variants
and now a Nachi variant. Thursday also saw the arrival of a Trojan, called
Mitglieder.H, with the ability to spread to computers infected with the
MyDoom.A worm.

OK, so you're a Ph.D.  Just don't touch anything.
