Operating system reinstallation

Reinstalling the operating system is another approach to virus removal. It involves simply reformatting the OS partition and installing the OS from its original media, or imaging the partition with a clean backup image (taken with Ghost or Acronis for example).

This method has the benefits of being simple to do, can be faster than running multiple anti-virus scans, and is guaranteed to remove any malware. Downsides include having to reinstall all other software as well as the operating system. User data can be backed up by booting off of a Live CD or putting the hard drive into another computer and booting from the other computer's operating system.

Encryption of mail sessions

All relevant email protocols have an option to encrypt the whole session. Remarkably, those options prevent a user's name and password from being sniffed, therefore they are recommended for nomadic users and whenever the internet access provider is not trusted. On sending mail, users can only control encryption at the hop from a client to its configured outgoing mail server. At any further hop, messages may be transmitted with or without encryption, depending solely on the general configuration of the transmitting server and the capabilities of the receiving one.

Encrypted mail sessions deliver messages in their original format, i.e. plain text or encrypted body, on a user's local mailbox and on the destination server's. The latter server is operated by an email hosting service provider, possibly a different entity than the internet access provider currently at hand.

Behavior-based robotics or behavioral robotics

Behavior-based robotics or behavioral robotics or behavioural robotics is the branch of robotics that incorporates modular or behavior based AI (BBAI).

The school of behavior-based robots owes much to work undertaken in the 1980s at the Massachusetts Institute of Technology by Professor Rodney Brooks, who with students and colleagues built a series of wheeled and legged robots utilising the subsumption architecture. Brooks' papers, often written with lighthearted titles such as "Planning is just a way of avoiding figuring out what to do next", the anthropomorphic qualities of his robots, and the relatively low cost of developing such robots, popularised the behavior-based approach.

Brooks' work builds - whether by accident or not - on two prior milestones in the behavior-based approach. In the 1950s, W. Grey Walter, an English scientist with a background in neurological research, built a pair of vacuum tube-based robots that were exhibited at the 1951 Festival of Britain, and which have simple but effective behavior-based control systems.

The second milestone is Valentino Braitenberg's 1984 book, "Vehicles - Experiments in Synthetic Psychology" (MIT Press). He describes a series of thought experiments demonstrating how simply wired sensor/motor connections can result in some complex-appearing behaviors such as fear and love.

Developmental robotics

Developmental Robotics (DevRob), sometimes called epigenetic robotics, is a methodology that uses metaphors from developmental psychology to develop controllers for autonomous robots. The focus is on a single robot going through stages of autonomous mental development. Researchers in this field study artificial emotions, self-motivation, and other methods of self-organization.

DevRob is related to, but differs from, evolutionary robotics (ER). ER uses populations of robots that evolve over time, whereas DevRob is interested in how the organization of a single robot's control system develops through experience, over time.

DevRob is also related to work done in the domains of Robotics, Artificial Life.

Similar to developmental robotics, Epigenetic robotics is an interdisciplinary research area with the goal of understanding biological systems by the integration between neuroscience, developmental psychology and engineering sciences. Epigenetic systems are characterized by a prolonged developmental process through which varied and complex cognitive and perceptual structures emerge as a result of the interaction of an embodied system with a physical and social environment. An additional goal is to enable robots to autonomously develop skills for any particular environment instead of programming them for a specific environment.
