A flawed McAfee antivirus update sent enterprise administrators scrambling today as the new signatures quarantined a crucial Windows system file, crippling an unknown number of Windows XP computers, according to messages on the company's support forum.
The forum has since gone offline.
Computerworld understands TVNZ is one prominent local victim of the rogue update with several hundred PCs, around 30 percent ot the company's fleet, affected.
Meagan Richards, of TVNZ corporate affairs, says a couple of hundred PCs were affected at the broadcaster and staff have been working since 4 am to restore them "PC by PC".
Richards said the job was almost complete when spoken to at 9.15 am today.
However, another source put the number of PCs hit at TVNZ at close to 1,000 and says the issue started around 2.30 when a support machine rebooted.
