Protect yourself against Computer Worms
Computer worms, like SQL Slammer and Blaster, that spread through vulnerabilities in network services can best be protected against by keeping the anti-virus up to date and installing patches that operating system and application vendors provide.
Computer worms that spread like Trojan Horse can best be defended against by not opening attachments in e-mails. These infected attachments are not limited to .EXE files. Microsoft Word and Excel files can contain macros that spread infection.
