Anti-spam firm Blue Security was shuttered when a spammer issued DOS attacks, threatening the company and affecting operations of some of its users.
Internet security firm Blue Security closed operations when its aggressive tactics angered a spammer enough to issue DOS (define) attacks to the company and five top-tier hosting providers in the U.S. and Canada.
Integrated message management firm Postini found that out of 22 billion messages evaluated last month, 18.5 billion were considered unwanted. That means unwanted email, or spam, accounted for 84 percent of email in April. It is, however, 1 percent down from March.
The number of quarantined viruses remained about even with March levels. Twenty-eight million viruses were stopped by the security firm.
