Some of the security issues for Internet users to be aware of include: - Hackers: Hackers are users who work to find loopholes in Internet security systems and exploit those loopholes. Their intentions could be anything from a desire to copy confidential information to generally just trying to cause trouble. Regardless of a hacker’s purpose, Internet users are at risk and should ensure that they safeguard their computer and personal information.
- Viruses: Viruses are computer programs designed to infiltrate unsuspecting user computers, replicate themselves, spread to other computers, destroy data, and interfere with the operation of your computer. Viruses are most commonly spread through attachments in E-mails, instant messages, or other downloads.
- Spyware: Spyware is software that plants itself on your computer and collects personal information, usually for the purpose of targeting advertising. Adware is spyware that allows advertisements to pop up on your screen based on the information it has gathered from your hard drive. Not all spyware is harmful, but it generally ends up on your computer without your consent and users need to be aware of it, as it can disrupt your computer’s performance.
- Worms: A worm is a program that replicates itself and sends itself to other computers on your network, usually undetected. While a virus has to attach itself to an existing program, a worm does not–it can replicate and spread on its own. Worms can shut down computer function because of the bandwidth they use.
- Phishing Scams: Phishing is essentially tricking a computer user into giving away valuable personal information such as bank account numbers, social security numbers, and credit card numbers. In a phishing scam, the user may receive an E-mail that appears to be sent from their bank asking for the user to confirm personal information. The goal of a phishing scam is to use this information against the victim of the scan.

- Spam: Spamming is the act of sending messages to multiple users indiscriminately in an attempt to flood the Internet with advertising or other information. While spam itself will not likely harm your computer, it can be a nuisance and distraction from the web content you’re really looking for. It’s also easy to hide viruses in links provided through spam messages.
There are ways to protect yourself from the above internet security issues. First, make sure that your computer is equipped with anti-virus software to detect and eliminate security issues. Second, make passwords difficult to guess and change your passwords often. Third, install updates as they become available. Finally, be smart about your online activities. Refuse to click on links that are from unfamiliar or suspicious sources. These issues can be hard to detect, but the available security measures should take care of most issues.
