What is a Computer Virus or a Computer Worm? Viruses require an active host program to cause damage and infect other executable files or documents, while worms are stand-alone malicious programs that can self-replicate and propagate via computer networks, without human help.

How Fast Do Composting Worms Multiply? In the wild, worms can move through the soil to find a temperature that suits them, but you must protect worms living in composting bins from extremes. Composting worms reproduce best when they are kept between 55 and 77 degrees Fahrenheit, with the ideal temperature hovering in the range of 60 to 70 degrees. Reproduction. Worms are hermaphroditic -- each one has both male and female parts -- but generally speaking, it still takes two to make babies. Sparse populations of worms may be slow to reproduce, but as a general rule, a worm at least 60 days old can find a mate and produce a cocoon that contains an average of four babies. Typically, a population of composting worms doubles every three to six months.

How are tapeworms transmitted? The tapeworms form cysts within the intermediate host (different locations for different tapeworm species). The definitive host is then infected when they eat the cysts (while eating the meat of the intermediate animal-hence the intermediate animal is usually prey).

Worm Composting Basics Worm composting is using worms to recycle food scraps and other organic material into a valuable soil amendment called vermicompost, or worm compost. Worms eat food scraps, which become compost as they pass through the worm's body. Compost exits the worm through its' tail end.orms can live for about one year in the worm bin. If a worm dies in your bin, you probably will not notice it. Since the worm's body is about 90% water, it will shrivel up and become part of the compost rather quickly.

How Does a Virus Infect Your Computer? Unlike viruses, worms do not have to attach themselves to a program in your computer, and may not damage files on an infected computer. Instead, worms more often slow down computer networks by eating up bandwidth, or your computer's ability to prcess data, as the malware replicates and spreads.hough they're not a living thing like you and me, computers can get sick from viruses, too. A computer virus is a software program designed to replicate itself and spread to other machines.

A definition of malware Viruses and worms are defined by their behaviour – malicious software designed to spread without the user’s knowledge. A virus infects legitimate software and when this software is used by the computer owner it spreads the virus – so viruses need you to act before they can spread.omputer worms, on the other hand, spread without user action. Both viruses and worms can carry a so-called “payload” – malicious code designed to do damage. Trojans and Rootkits – the masked threat. Trojans and rootkits are grouped together as they both seek to conceal attacks on computers.

COMPUTER WORM Computer worms are among the most common types of malware. They spread over computer networks by exploiting operating system vulnerabilities. Worms typically cause harm to their host networks by consuming bandwidth and overloading web servers.Computer worms can also contain “payloads” that damage host computers. If the scan detects a computer worm or other malware, use the software to remove malware and clean or delete infected files. 2  A scan that detects no malware is usually indicative that symptoms are being caused by hardware or software problems.

How Fast Do Compost Worms Reproduce? Reproduction of red worms (Eisenia fetida) is important because their waste products, called castings, provide key soil nutrients that are beneficial in gardening and the environment. Reproduction. Red worms reproduce when they reach maturity, which is marked by the formation of an external egg sac at about 90 days of age. In ideal conditions thereafter, each red worm produces a cocoon containing about 20 juvenile worms each week. Ideal Conditions. Red worm reproduction is most successful in a healthy environment.

Worm Lady Worms have a very interesting method of reproduction. There are no male and female worms – all worms are the same and each produce both sperm cells and egg cells. When a worm is mature and ready to reproduce, it finds a partner worm. They line up head to head attaching themselves together at the clitella (the thick light colored band around each mature worm) and mucous is secreted . The sperm cells are exchanged by the worms through this mucous.

Nimda Nimda can infect files over networks. Because of its file infection ability, it is possible to transmit the worm by moving a stand-alone executable program through a floppy or flash disk. In most cases it avoids infecting the WINZIP32.EXE file. It will not infect files when run from a file other than ADMIN.DLL.
