A program similar to spyware but its purpose is to force the display of advertisements on the infected computer.
A software designed to prevent, search for, detect, and remove software viruses, worms, trojans, spyware etc.
A number used with an algorithm to hash data in a way that can be "unhashed" only by using the same or a related number.
A method used legitimately to prevent potential errors when multiple programs try to access the same resources or critical files. This feature can be abused by spyware/adware to block its own removal.
- A program designed to block (unauthorized) access to specific ports or applications.
- A computer configured as a router which includes firewall software that can restrict access between the networks it manages.
A computer or software that can identify malicious network activity and alert the administrators of this activity. Tripwire and Snort are two IDS that runs on Linux distributions.
An attack that can take several forms, although most begin with the receipt of a seemingly legitimate email. Over time they have evolved from a simple request via email for your personal and/ or financial information to today's more sophisticated attempts to install crimeware on your computer. .
