Common Threats:

Viruses: A virus is a software program which attaches itself to another piece of software.  The virus inserts its code into a file which when executed, runs the virus.  A boot virus is a program which runs when the computer starts.

Spyware: Spyware is software which works in the background to gather a user's information and behavior.  This information is then transmitted to another party.  Spyware works in the background without a user's knowledge.  Some of the information can include the operating system of the computer, the type of browser, the computer IP address and where a user browses to.

Trojan: A Trojan is a software program which runs in a computer as a secret agent of the attacker.  Trojans do not replicate themselves like worms or viruses.

Worm: A worm is a program which replaces files.  They can be as destructive as viruses, and like a virus can replicate itself.

Browser Hijacking: A browser hijacking occurs when a browser gets set to a website which is not the user's choosing.  Sometimes information gets rerouted to another site without the user's knowledge and makes the Internet connection run slower.  Hijacks cna change a user's homepage.

Spoofing: Spoofing if when an identity gets forged.  The attackers forge their IP address with the person they want to attack, overloading the victim's Internet connection.

Phishing: Phishing happens when a person send out email masquerading as a trusted company or person.  Typically the email states the user's account information needs to be updated and provides a link to do so.  The link redirects the person to a webpage which looks legitimate, but is not, and actually captures confidential information such as credit card number, bank accounts and social security numbers.

Adware: Adware is software which directs specific ads to your computer.  This typically happens after you consent to loading some free software program or browser helper.  Some Adware also tracks your Internet browsing and reports this information back to a central server.

Popup: A popup happens when a new browser window opens up on it's own.  Sometimes so many popup windows can open, it renders the computer useless.
