Computer users today are still familiar with the problems caused by computer viruses. This problem arises because always the emergence of new variants are always adapted to the existing anti-virus applications. In addition the system security holes that can be utilized by the virus is always found in the virus makers. Based on these problems, the authors build a viral application that is evidence that the existence of security holes in computer operating systems that can be utilized by the virus. And in the same case writers built a antivirus application that can handle viruses that are able to adapt and also close the gap that can not be solved by other antivirus applications, where the gap can still be utilized by the virus in a computer attack victim. Virus that was built is a viral application that has several capabilities that include the ability to hide, the ability to multiply, the ability to find and check the target of attacks, and the ability to manipulate the system. Virus applications built using waterfall process model. Applications can be called with the virus Qvir, built using Delphi 7 programming language. As for antivirus applications are built using the CRC32 method as a way for naming a file and also for the introduction of a file identified as potential viruses. Antivirus application can be called with AntQ, built using programming language Visual Basic 6. Virus applications built to find out the gap that has the potential to use viruses that can damage the security of computer systems in use, while the antivirus application is built to cover the gap from the computer system as well as gaps that have not been addressed by other anti-virus, so the virus can not enter and damage the system computer.
Applications viruses and antivirus applications are built are expected to increase knowledge about how the computer user from a computer virus to attack the victim. And also once able to gain more knowledge about how to survive an antiviral against virus attacks and also normalize the operating system re-work that had been attacked by a virus.
