Crystal Ferraro submits After a slow start late last week, spread of the mass-mailing worm soared on Monday as enterprises returned to work worldwide. UK-based e-mail scanning outsourcer MessageLabs intercepted 56,669 copies of the worm by midmorning Tuesday. More than 33,000 copies were caught on Monday.
The antivirus vendors have responded. Tokyo-based Trend Micro has bumped its alert to medium risk based on a high rate of infection in Korea. Likewise, McAfee Security has also raised Fizzer to a medium risk. Symantec has raised the worm from a Category 2 to a Category 3 threat because of its progress.
But at least one antivirus vendor thinks Fizzer has peaked. "We think the level is dying down and it peaked yesterday," said Chris Belthoff, senior product marketing manager at UK-based antivirus software vendor Sophos LPC.
