The country’s largest ISP Xtra is filtering the hoax virus doing the rounds of New Zealand users at the moment, even though the virus isn’t real.
The warning regards the sulfnbk.exe Windows file located in the C:\Windows\Command. According to the warning, on June 1, this file will wipe out the hard drive of whatever computer it is installed on. However, sulfnbk.exe is a Microsoft Windows utility used to restore long file names.
The hoax virus, which originated in Brazil, has caught out a number of users around the world and Xtra spokesman Matt Bostwick says the company has taken the unusual step of filtering emails based on the file name itself since there is no attachment to block.
Another virus, the Magistr worm, does delete this sulfnbk.exe file so if users find it is missing from their Windows/Command folder they should follow the instructions to replace it.
