Learn About Online Security

Security threats abound on the Internet. Browsing the Web and downloading files can put the user at risk for computer viruses, spyware, tracking cookies, and more. But by recognizing how these threats invade your computer and by taking the necessary steps to protect yourself, you can surf the Web with peace of mind.

Computer Viruses and How to Protect Yourself

Computer viruses are hidden computer programs that infect your computer. Usually transmitted through email, these malicious viruses can copy themselves onto your hard drive and cause malfunctions in your programs or, in extreme cases, crash your computer.

To protect yourself from computer viruses you need anti-virus software. This software is generally pre-installed when you purchase a computer, or you can purchase anti-virus software from any number of manufacturers online. Since anti-virus software is updated continually to respond to new threats, if you set your software to update automatically you will always have the best protection available.

Spyware Threats and How to Remove Them

Spyware is software that is installed on your computer without your knowledge. It is used to collect information about you such as your Web browsing habits and what websites you've visited. Spyware can also cause malfunctions in your computer such as changing settings, redirecting your browser, slowing connection speeds, and installing additional software.

Spyware distributors use tricks to get you to install their hidden software. It may be piggybacked in other software that promises enhanced computer performance if you install it, or through pop-up ads. Most leading anti-virus companies have bundled or stand-alone anti-spyware software that prevents and removes most spyware. Again, set it on automatic updating for best results.

Web Cookies - Are They Dangerous?

HTTP cookies are helpful cookies that are used by websites you visit to store bits of information such as your user settings, website preferences, and shopping cart contents. This information is stored in your computer's browser to enhance your website experience. An example of this is shopping online and using the site's shopping cart. This would be impossible without HTTP cookies. One way to deal with these cookies is to set your browser to allow only "session cookies." Then these cookies will be allowed only when you're on the website and are deleted when you leave it.

The kind of cookies you should protect yourself from are tracking cookies which gather information about what websites you visit without your knowledge. Tracking cookies are used by advertising companies who then determine what type of ads you'll see when you're online. Many feel this type of cookie is an invasion of privacy. To avoid tracking cookies, set your browser security settings to block any third-party cookies. You can also use your computer's Internet tools to delete any cookies before you close your browser.
