Even a budget gaming pc will cost around 125k NRS ~ 1111$ (US$) here in Nepal which can be available for just under ~650$ in other countries with the same specs. Even though, I have collected some information for you to build an entry-level and budget gaming pc here in Nepal. Entry Level Home/Office Build...

Types of Computer Viruses | Types of Viruses on Computer

Types of Computer Viruses Types of Viruses on Computer On the basis of their ways of infecting, viruses can be categorized into various types. Among them some common types of computer viruses are described below. Boot Sector or Start up Infector Virus: It is also called Boot record infectors virus. Start up infector virus infects the boot record or Master Boot Record (MBR) of the disk and replace the boot record program, copy elsewhere or overwrite it. This type of virus is loaded during the booting time and create the bad sectors on the disk and affect the entire computer system. This virus generally hides in the boot sector, in either the bootable disk or the hard drive. Boot Infector or Operating System Infector Virus: This is a common type of computer virus which infects the various parts of the Operating System or Master Control Program (MCP) and deletes and corrupts the system files necessary for booting. Thus, when these files are corrupted the O...

Evolution of Computer Viruses and Anti-virus

Evolution of Computer Viruses and Anti-virus The roots of the modern computer viruses go back to 1949 when Hungarian mathematician, JOHN VON NEUMANN introduced the concept of replicating computer program. He presented a paper on the "Theory and Organization of Complicated Automata," in which he postulated that a computer program could reproduce. This theory was tested in the 1950's at Bell Laboratories when a game called "Core Wars" was developed, in which players created tiny computer programs that attacked, erased and tried to propagate on an opponent's system. In 1983, American electronic engineer FRED RICK COHEN first introduced the term "COMPUTER VIRUS" to describe a self-replicating computer program. In 1987 two Pakistani brothers AMJAD and ALVI created the world's first PC virus named "C-Brain". The brothers created the virus to stop pirated copies of software software developed from Alvi's Brain Computer Shop. This viru...
