Symantec, the anti-virus software company, said it tracked an average of seven new Internet security vulnerabilities per day in 2003.

In a report being released today analyzing recent Internet threats, Symantec researchers said that one of 2003's most significant events occurred in August, when three severe worms surfaced within 12 days. Blaster, Welchia and Sobig.F infected millions of computers and may have resulted in up to $2 billion in damage, according to the report.
