Victorian distributor, Westan, is fighting a 'low risk' virus that almost forced it into an early Christmas closure.
The accounts department were first to notice sluggish system performance yesterday afternoon when the w32/looked/bh virus hit.
"The virus almost shut us down," managing director, Victor Aghtan, said. "The servers were hit and we use IP telephony so the phone system went down.
"It's rated as a low-risk virus but it came through every desktop. We had guys working all night but they couldn't do anything with it. We can clean it up but it comes back so we are trying to find out where it's hiding."
The problem has been reported to Microsoft but the software giant said it was not aware of a widespread outbreak.
"It's lucky we are shutting down [for Christmas] anyway and have time to clean this up," Aghtan said. "Hopefully it won't cost us too much because the phones are back up and we have still been receiving orders by fax."
Westan closes on December 22 and reopens for business on January 2.
