The so-called "internet doomsday" for PC users is quickly approaching and, without access to the World Wide Web, business owners say work would grind to a halt.

"It would be disastrous. I mean, absolutely. It would stop my business," says local web designer David Eleuterius.

He says having no internet access is simply not an option.

"I'm constantly sending files back and forth with clients and communicating with them through the web."

"I keep most of my files online so if I ever lose a computer, I can always access those files from anywhere," explains Everardo Recendiz, a business coach in Shreveport.

Recendiz says he's not too worried about the "doomsday virus" set to hit on July 9th, and neither should you -- if you've got anti-virus and malware protection.

"If your system is not up to date, there could be exploits or holes or other issues with your computer that those sites would be able to take advantage of," says Robert Breedlove, IT Director at Evergreen Presbyterian Ministries in Haughton.

Simply put -- the virus redirects your internet to malicious fake websites, wreaking havoc with your computer's DNS -- or address book.

"[The perpetrators] would have thousands, if not millions, of computers to utilize that computing power to make another attack or utilize it for other malicious intent."

The DNS Changer virus was first detected by the FBI last year, when a group of people were charged with using malware programs to hijack millions of computers across the globe.

The FBI's safety net against the DNS Changer will be removed on Monday, making your computer vulnerable if no protection is in place.

This could affect about a 125,000 computers world wide and about 40,000 here in the U.S.

So what exactly is a DNS? That's short for domain name system.

It converts user-friendly domain names -- like Yahoo -- into the numerical IP addresses that computers understand.

DNS servers are critical components of a computer's operating system.

Without them, you'd be unable to access websites, e-mail and any other internet services.

Computer experts suggest using multiple tools to make sure you have a wider net of virus protection options.

Scanning your computer regularly is always a good idea to make sure that virus and malware definitions are up to date.
