MyDoom uses search engines to find email addresses for propagation

The new MyDoom variant scans your HDD for domains (e.g. craphound.com), then hammers on search engines looking for valid email addresses at that domain (e.g., "GET /default.asp?lpv=1&loc=searchhp&tab=web&query=e-mail+example.com"). The traffic got so bad that it actually took Google down for a while.
