A new outbreak of computer viruses threatens to disrupt business networks and damage personal computers.
They include names like "blaster", "so big" and "love san".
Any computer connected to the Internet can be vulnerable, without proper protection.
"If you're computer is acting unusual in any way, you should get it looked at," said computer technician, Sue Westgate.
The technician finds and fixes computer problems daily. Her best advice about viruses is prevention.
"Some viruses, they just put annoying little signs up and say something obnoxious and then go away. Others will re format your drive," Westgate explained.
Anti virus software is designed to identify and eliminate viruses and worms. But it's important to keep your protection upgraded. Trouble is, too many consumers don't keep current.
"A lot of it is lack of knowledge. A lot of people will take, will buy an anti virus program and never update it," she said.
Businesses must be constantly vigilant in keeping their computer networks protected and secure.
The computer expert at WLOX is responsible for keeping some 150 computers virus free.
Mark Pardee monitors the network and keeps the anti virus software current. A computer network demands multiple layers of protection.
"And I think that's the key for any business. You can't just have virus protection on the desktop machines. You can't just have virus protection at the E-mail server. You have to have several different levels," said Pardee.
Solid protection will intercept the viruses and keep them from crashing the system.
"We don't even like to think about that nightmare," Pardee admitted.
Along with installing anti virus software, computer experts say you should be wary about opening any suspicious E-mail, especially those with unknown attachments.
