Computer Virus: Types and its actions

 imsev208-046

A computer virus is a computer program that can replicate itself and spread from one computer to another. The term “virus” is also commonly, but erroneously, used to refer to other types ofmalware, including but not limited to adware and spyware programs that do not have a reproductive ability.

Malware includes computer viruses, computer wormsransomwaretrojan horseskeyloggers, most rootkitsspyware, dishonest adware, malicious BHOs and other malicious software. The majority of active malware threats are usually trojans or worms rather than viruses. Malware such as trojan horses and worms is sometimes confused with viruses, which are technically different: a worm can exploit security vulnerabilities to spread itself automatically to other computers through networks, while a trojan horse is a program that appears harmless but hides malicious functions. Worms and trojan horses, like viruses, may harm a computer system’s data or performance. Some viruses and other malware have symptoms noticeable to the computer user, but many are surreptitious or simply do nothing to call attention to themselves. Some viruses do nothing beyond reproducing themselves.

There are lots of viruses available and are being developed periodically to compromise the data. Some of them are discussed here.

Merge Sort Algorithm

alg

Merge sort is based on the divide-and-conquer approach. Its worst-case running time has a lower order of growth than insertion sort. Since we are dealing with subproblems, we state each subproblem as sorting a subarray A[p .. r]. Initially, p = 1 and r = n, but these values change as we recurse through subproblems.
