This was first reported to me by one of the major forum owners. He told me that it seemed that Google was sending him 3 - 4 times the amount of traffic then what was of the norm. Later on he found the source was a virus:

The latest version of MyDoom, which started arriving in peoples mail boxes in force today, uses search eninges to find more recipients for its message.

Once the virus is started, it searched the users files for domain names. Once it spotted a domain name (e.g. '', or in '(Link: (Link:')')(Link:')'), it will search various search engines for valid e-mail addresses within these domains. These search engines include Lycos, Google, Altavista, Yahoo and possibly others. Some of the search strings used:

GET /default.asp?lpv=1&loc=searchhp&tab=web&

Some search engines report performance issues.

Antivirus vendors are currently publishing updated signature files. Please update ASAP. Infected machines can be identified by looking for excessive traffic to search engines and smtp traffic.

Search engines, such as Google, were reported to have been down. Articles by ZDNet were posted, Andy Beal posted a screen shot, and the folks over at SlashDot are discussing.
