Worm alert: Gigger's after your data

NEWS Anti-virus firm Symantec is warning of a new worm called "Gigger" which attempts to delete all files on a victim's computer and then re-format the hard drive. The company has labelled the new worm a high risk because of its destructive payload, despite the fact that it has seen only a limited number in the wild. It has the potential to spread very quickly using a traditional email mass-mailing technique. Users should beware of receiving an email entitled "Outlook Express Update" carrying file "mmsn_offline.htm". For more information see:
