Anti Virus Programs Compared

Why Anti Virus Software, a Must Have for Every Pc?
By definition, a virus is a computer program that is able to copy itself and infect other computers. The first one, according to Wikipedia, was seen almost half a century ago. The Creeper virus was detected in ARPANET, a predecessor of the World Wide Web. This code is compared to their virus dictionaries and if a match is found, the antivirus program attempts to clean the suspicious part, without damaging the original data. Another method of fighting viruses is to monitor computer activity, also known as heuristic analysis. It was using the modem connection to replicate on other PCs and when it achieved its goal, it displayed the following message IM THE CREEPER: CATCH ME IF YOU CAN. Anti virus software is another kind of computer programs that appeared because of the need to disinfect computers from viruses. Reaper was the first of its kind and its aim was the Creeper virus. You can visit Some people said that they might have shared the same creator, but this was never proved.
Since the first antivirus program, viruses and methods to fight them evolved rapidly. Most of the times, the next step in evolution is done by computer viruses and antivirus creators struggle to fight back and invent new ways to clean those pesky bugs. The common approach of antivirus software is to scan files, memory or registries from your computer and detect malicious code. This code is compared to their virus dictionaries and if a match is found, the antivirus program attempts to clean the suspicious part, without damaging the original data. Another method of fighting viruses is to monitor computer activity, also known as heuristic analysis. This includes monitoring memory and ports traffic for any signs of infection. A modern approach is the so called sandbox method. It involves running the suspicious file into a simulated operating system and analyzing the results. No matter the method, if a virus is found, the antivirus first attempts to disinfect the file. If its unsuccessful, or go to the infected file is quarantined (isolated from other programs) or in worst case, deleted.
Its very important to have a reliable antivirus program installed because there can be viruses on a file you download, inside an email attachment or even a website can include some malicious code to infect your PC. Some of the programs that are out there and can do the task are free, but most of them require payment. This code is compared to their virus dictionaries and if a match is found, the antivirus program attempts to clean the suspicious part, without damaging the original data. Reaper was the first of its kind and its aim was the Creeper virus. Another method of fighting viruses is to monitor computer activity, also known as heuristic analysis. Almost all include updates of their viruses database, to make sure your PC is protected to the newest threats. AVG AntiVirus Free, BitDefender Free, Comodo AntiVirus and PC Tools AntiVirus Free Edition are only a couple of the free antivirus programs available on the Internet.

What the Virus $111.53 Antivirus software is a key security technology on todays end user systems. Current antivirus engines use two complementary techniques to detect malware. One is to statically scan potential malware sample files for certain patterns which are known ( malware signatures ). The other is to dynamically detect typical malicious behavior (e.g., modifications of registry keys, DLL injections etc.) upon execution of a sample. No antivirus product can reliably detect malware. Rather, all products are plagued by false positives and false negatives. An interesting approach to improve the reliability of detection is to run several antivirus products on a given malware sample. There are several online scanning services, that implement this approach. However, for performance reasons these services only use the static signature detection functionality of the anti virus products, and thus do not take advantage of the full functionality of current antivirus engines. This book explains how to overcome this limitation and to build an efficient online malware scanning service that fully utilizes the capabilities of current antivirus engines.

Ah (Computer Virus) $68.51 High Quality Content by WIKIPEDIA articles Ah (also known as Tuesday and Jerusalem.Ah) is a very buggy computer virus which infects COM files including command.com. Ah is based on the V1024 virus, and originated in Italy in May 1991. When the first program infected with Ah is executed, Ah will install itself memory resident at the top of system memory, but below the 640K DOS boundary. After it is memory resident, Ah will infect .COM programs over 1K in length when they are executed. Infected programs will increase in size by 1,173 bytes, though the file length increase will be hidden if Ah is resident. Their date and time in the DOS directory will appear to be unaltered, though if the programs original time was 12:00a, it will now be blank. The virus will be located at the beginning of infected programs. Total system and available free memory, as indicated by the DOS CHKDSK program, will decrease by 1,216 bytes. Interrupts 08 and 21 will be hooked by the virus. Systems infected with Ah will experience frequent system hangs. Author: Surhone, Lambert M./ Tennoe, Mariam T./ Henssonow, Susan F.

Hare (Computer Virus) $68.51 High Quality Content by WIKIPEDIA articles The Hare Virus is a destructive computer virus which infected MSDOS and Windows 95 machines in August 1996. It was also known as Hare.7610, Krsna and HD Euthanasia. The virus was capable of infecting .COM and .EXE executable files, as well as the Master boot record of hard disks and the boot sector on floppy disks. A computer virus is a computer program that can copy itself and infect a computer. The term virus is also commonly but erroneously used to refer to other types of malware, including but not limited to adware and spyware programs that do not have the reproductive ability. A true virus can spread from one computer to another (in some form of executable code) when its host is taken to the target computer; for instance because a user sent it over a network or the Internet, or carried it on a removable medium such as a floppy disk, CD, DVD, or USB drive.
