Difference Between A Worm And A Virus

What is the difference between a worm and a virus?

Virus Vs. Worms: Virus and worms are malicious programs that reach our computers via CDs, USB sticks, attachments and files downloaded from the Internet. One of the main differences is that worms do not require user intervention to replicate while virus replicates as the user executes the infected file. There are many differences between a worm and a virus, which are listed below:

What is the difference between a worm and a virus?

 

1. Worms spread automatically while the virus needs the help of humans to spread:

The worm does not need a host file. It is an autonomous program that finds a vulnerability in the system or network and enters this system. Once a worm has infected a computer, it can spread to the entire network and reach other networks to which the system is connected. The virus needs human help to run. When the user runs the host file that contains the virus, it starts to propagate in the system. Some viruses replace programs with their instances. It can also delete, duplicate or damage files.

2. Worms do not affect the file, but increase resource consumption to crash the system or network while Virus destroy, corrupt or corrupt files on the infected computer:

Worms tend to increase the use of resources such as memory, processor or network bandwidth. You can block a PC or network by increasing usage. Worms exploit a network or system vulnerability and infect the computer. It has recently been discovered that some worms use social engineering tips to trick users into entering their system. The virus spreads from computer to computer and damages user data. It can be replicated and attached to another application or file.

3. Worms do not need a host and exploit the vulnerability of a network to spread while virus attaches to the host and spreads to where the host reaches:

The worm is a kind of virus, replicating itself and moving from system to system. Worms are standalone computer malware that does not require hosts to propagate. He does not need human help to run. The worms replicate and propagate automatically through the user’s network or e-mail account.

4. Worm propagation speed is high and infects multiple computers or networks, while virus propagation speed is low compared to worms:

Unlike traditional viruses, worms are not tied to a file or program. Instead, they invade computers and appear through a network vulnerability, replicating and propagating automatically before you can remove the worm. By this time, however, they will have already consumed the full bandwidth of the network, interrupting and stopping the large networks and web servers.

5. To remove worm infections or prevent infections, the user needs an anti-virus program and a firewall to clean up the infection or stop the infection while for the virus the user needs an antivirus program only:

To prevent infection with worms, you must install the anti-virus program and an active firewall. In addition, you must regularly update the operating system and other software. Worms often exploit the vulnerability of other software to invade the system. To prevent infection with the virus, the user does not have to make much effort. You need an antivirus program to stop his attack
