"The pesky Netsky worm family once again occupied a vast majority of the positions in May. However, the largest virus epidemic for the month was Worm/Sasser," said Steven Sundermeier, Vice President of Products and Services at Central Command, Inc. "Discovered on April 30th, Sasser quickly raged havoc across the Internet and crippled thousands of Windows systems worldwide. Many spooked Windows 2000 and XP users found their computers continually rebooting for no apparent reason, a common sign of a Sasser infection." Sasser spread by exploiting a known Windows LSASS (Local Security Authority Subsystem Service) vulnerability.
Vexira Antivirus has been updated for 1623 different viruses, worms and other malicious applications during the month of May 2004.
