Antivirus Programs
Today, people rely on computers to create, store, and manage critical information, many times via a home computer network. Information transmitted over networks has a higher degree security risk than information kept in a user’s home or company premises. Thus, it is crucial that they take measures to protect their computers and data from loss, damage, and misuse resulting from computer security risks. Antivirus programs are an effective way to protect a computer against viruses. An antivirus program protects a computer against viruses by identifying and removing any computer viruses found in memory, on storage media, or on incoming files. When you purchase a new computer, it often includes antivirus software. Antivirus programs work by scanning for programs that attempt to modify the boot program, the operating system, and other programs that normally are read from but not modified. In addition, many antivirus programs automatically scan files downloaded from the Web, e-mail attachments, opened files, and all types, of removable media inserted in the computer (Karanos 201-205). One technique that antivirus programs use to identify a virus is to look for virus is to look for virus signatures, or virus definitions, which are known specific patterns of virus code. According to Shelly and Cashman (Antivirus programs), many vendors of antivirus programs allow registered users to update virus signature files automatically from the Web at no cost for a specified time. Updating the antivirus program’s signature file regularly is important, because it will download any new virus definitions that have been added since the last updates. Methods that guarantee a computer or network is safe from computer viruses simply do not exist. Installing, updating, and using an antivirus program, though, is an effective technique to safequard your computer from loss.

There are several types of worms, viruses, Trojan horses and spyware, which can be delivered in a variety of ways. Computer viruses are a type of software or executable file that attaches itself to other programs to be uses. Viruses can cause system failures, rewrite hard drives, or destroy files and programs.

Based on the results, the bunchberry plant, with a scientific name of Cornus canadensis, was most frequently seen in station four, the ecotone, and second most in station five, the forest which is most likely in the lower forest since it has a similar environment to that of station four, and third most in station three, the bog. It was not as frequently seen in areas of higher elevation such as the old field. It should be noted that all three locations were very moist which is expected since they receive water from the marsh. Due to its more frequent presence in moist environments, it is predicted that the bunchberry is more adapted to such locations. It is also predicted that sandy soil supports its growth since it was mostly seen in stations four and five which have sandy soil. Within and on the soil, lots of wood could be seen on the ground from remains of trees that were around the bunchberries which lead to a possibility that as the wood remains are buried in the soil, the bunchberry plant is able to use it to build roots.…

Tens of thousands of new viruses or modified versions of old viruses are released each year. • Viruses normally attempt to hide within the code of a host program to avoid detection. Viruses, by definition, have a method to spread themselves. • Any computing device such as a smartphone, notebook, netbook, or iPad can be infected with a virus. Even your car, which now contains embedded computer systems, could catch a virus, especially if it connects to the Internet for software updates.…
