Network Security & Network Support

Spyware is a serious threat to corporate and home networks as it is becomes more and more prevalent. Unlike many other threats, it is remarkably hard to identify and remove. Following are some types of Spyware that are looking for you, the most common symptoms that may indicate a problem, and solutions to those problems.

By definition, Spyware is a program that is loaded on to your system without your permission or knowledge. The program exploits a user’s lack of understanding, security flaws, or uses outright deception to gain entry to your computer to begin collecting data. Spyware is often confused with Malware, a program that is designed to cause damage and computer problems by introducing errors and disrupting systems.

Common Signs of a Spyware Infection

• Pop-ups
• New or modified internet toolbars
• New browser home page
• Computer is suddenly sluggish
• Computer is slow to start up or shut down
• Strange errors that appear during shut down such as “end task” or “cannot close program”

Things You Should Know and Do

• Every effort you can expend NOW to prevent infection LATER is well worth it
• Be very conscious of spyware and the company network
• Scan your machines with systems like Anti-Virus, Anti-Spyware, Anti-Spam and Firewall
• Update all machines as frequently as possible

Spyware can take many forms, most of which fall into the category of nuisance or annoyance. Spyware on a home computer can compromise sensitive data such as credit card or banking information. It can also make your email address and other personal information available to marketing firms or criminals. Spyware can also corrupt your files, and downgrade the performance of your computer. Within a corporate environment, Spyware can also markedly reduce the overall performance of the entire company information system and compromise sensitive, mission critical data.

Spyware and Malware cannot be prevented completely, but they can be mitigated and removed. As quickly as anti-Spyware and system patches are developed, programmers develop newer and more resilient programs. For this reason, the recommendations in this paper are meant to be considered best practices and not absolute cures or absolute preventative measures. A company information system is a vital part of your business, and must be actively maintained. Proper maintenance and preventative measures can help you identify and eliminate problems before they result in a crisis.
