According to comScore Media Metrix's top 50 U.S. Internet properties for the month of August 2003, leading virus protection providers Symantec and McAfee.com both broke into the top 50 in response to
the SoBig and Blaster outbreak, with 29 million and 11 million unique visitors respectively. The traffic spikes driven by SoBig and Blaster were strong enough to be felt even at the category level in
both the Computer Software and Technology - News categories, which grew faster than all other categories in August.
