An Outlook e-mail attachment similar to the love bug that wreaked havoc a fortnight ago is dodging the best efforts of network administrators by changing its name each time it's sent.
When opened the Visual Basic Script virus sends itself to all recipients in the user's address book.
The virus then renames itself with the name of a system file so that subsequent recipients can't be forewarned as to what title to look for in the message's subject line.
The subject line says "FW:" followed by the new name, preventing systems administrators from using filtering software to block e-mail messages that carry the virus.
The computer crashes shortly after infection meaning that Windows must be reinstalled.
The filename attached will have one of the following extensions: Doc.Vbs, Xls.Vbs, Mdb.Vbs, Bmp.Vbs, Mp3.Vbs, Txt.Vbs, Jpg.Vbs, Gif.Vbs, Mov.Vbs, Url.Vbs, and Htm.Vbs
Trend Micro already has a patch available on its site at www.antivirus.com.
The virus has already knocked systems over on the US West Coast, with one company reporting that 5,000 computers were infected by the virus yesterday.
