DeKALB | For many people, computers have become a necessity. Yet some people are still unaware of how to protect their personal data from online dangers.

According to OnGuard Online, a government website made up of information from federal agencies and technology industry experts, it is important to have anti-virus software.

David Gunkel, professor of media studies, said it’s very important to install anti-virus software on personal computers to avoid damage to data.

“The Internet is the natural environment of the computer virus,” Gunkel said. “It is where viruses live, reproduce and proliferate. Some can be quite destructive to user systems and data.”

OnGuard Online gives tips on how to protect against Internet fraud and how to secure personal computers and information.

The website also states it is important to check and make sure the wireless network you are using is secure. Gunkel said to be cautious when connecting to a wireless network.

“Just because a network is listed as secure does not necessarily mean that it has an appropriate level of security to handle the protection of personal data,” Gunkel said.

Sycamore resident Anna Ortiz said she always had virus protection on her computer.

“I think it’s very important,” Ortiz said. “I got it after I had to get a new computer because my old one got infected with bad malware and viruses.”

Sophomore journalism major Martha Lueck said it is important to protect personal computers and to avoid websites that may be harmful.

“I like using websites that don’t screw up my computer,” Lueck said. “There’s no point in using a website that could potentially damage my computer.”

Gunkel said it’s important to only give the data that is needed to complete a transaction over the Internet.

“If an e-mail or website form asks for information that seems to be unnecessary or unrelated to the intended transaction, it is better to avoid providing it,” Gunkel said.

Gunkel said people also need to be careful on social networking sites.

“Think before you post personal information on a social network like Facebook,” Gunkel said. “Exercise some thoughtful discretion by asking yourself whether an intended post of profile update exposes you or your information in any way.”
