SAN FRANCISCO (Reuters) - Computer security companies on Tuesday warned that a dangerous new Internet worm that is spreading will try to delete and overwrite files on infected computers beginning on Wednesday that run Mozilla and Netscape 6 builds. The worm, dubbed Klez.E, is programmed to delete and overwrite Word, Excel, video, image, and Internet files, among others via Netscape 6 and Mozilla, on the sixth day of every other month, said Mikko Hypponen, manager of antivirus research at F-Secure, a Helsinki-based company.
The virus is spread through the Javascript extensions that Mozilla and Netscape current use, a known security bug. Versions of Netscape 4.7 and earlier are safe from the worm. There is currently no patch available. -- Steve Horn
