• Computer worms can be remotely controlled while the viruses are independent. A virus is a computer program that attaches itself with a file and then transfers from computer to computer and corrupts the user data. The Main Difference Between Virus and Worm. On the other side, a worm is a malicious program that is able to replicate and transfer from one computer to another through the network and corrupts the user data. Computer viruses, much like their biological namesakes, are designed to “replicate” rapidly once they enter the host (in this case, a computer). Worms automatically execute and spread. It is a hidden piece of code which steal the important information of user. Trojan Horse: Trojan Horse does not replicate itself like virus and worms. Computer viruses are … What sets them apart is the way in which they self-replicate, with viruses requiring the aid of users, while worms are able to act on their own. A worm is a standalone program that can self-replicate and spread over a network. • The viruses infect the files in the computer while worms consume the resources excessively such as the bandwidth and make the system slow and unstable by replicating and running the programs in memory. Worms. Computer viruses operate in a way that is not so different from those that affect us. A computer worm is a type of malware that spreads copies of itself from computer to computer. How viruses replicate. Viruses destroy, damage, or alter the files in the infected computer. Worms can be transmitted via software vulnerabilities. Computer Worms. Any savvy computer user knows to watch out for viruses. • Viruses are slower than computer worms. Worms, unlike viruses or trojans, take advantage of a computer’s pre-existing security vulnerabilities at an operating-system level. A graduate student created the first worm (the Morris worm) in 1988 as an intellectual exercise. Virus attaches itself with the host and spread where the host reaches. A worm’s autonomy tends to make it more aggressive or contagious, while a virus may lay dormant for years waiting for a user to open an infected file. Unlike a virus, a worm spreads by exploiting a vulnerability in the infected system or through email as an attachment masquerading as a legitimate file. Malicious software, or “malware” is a type of program created specifically for deleting, modifying, copying, or changing file format of data, or disrupting the PC operating system or local/global networks. To use a cinematic analogy, worms are more like predators, viruses are more like aliens. Worms can be controlled by remote. can help keep you safe online. As I’ve already mentioned before, both viruses and worms can cause major damage to your organization and spread quickly. Virus Worm The virus needs human help to execute and spread. Not every virus is devastating, but some can wreak havoc on your computer. What came first, the virus or the worm? It replicate itself more and more to cause slow down the computer system. The idea of a virus infecting a computer system was first an academic article called “Theory of self-reproducing automata” published in 1966 by Professor John von Neumann of the University of Illinois. Virus. Worms is also a computer program like virus but it does not modify the program. It can replicate itself without any human interaction and does not need to attach itself to a software program in order to cause damage. Worms are also standalone software or files, and they typically travel across a computer network (your home or work network, for example), rather than through software downloads. Worms don’t need a host and exploit the vulnerability of a network to spread. OK, hold up. Or a worm in your hard drive?
