What is the difference between a virus and a worm?
Viruses and worms are often lumped together in the single category of virus, which confuses many people. What do a virus and a worm have in common and how do they differ from each other? Viruses and worms belong to a class of software called malware. Malware, also known as malicious code, is short for malicious software which is designed to damage, disrupt, steal, or in general inflict some other “bad” or illegitimate action on data, hosts, or networks.
A virus is actually a piece of computer code that must replicate itself. For example, it may replace other executable files with a copy of the virus infected file. A virus can be spread by attaching itself to a host program shared with or sent to another computer system. In effect, this type of malware cannot spread unless a user sends or shares a file. Viruses can vary as far as how much damage they can do, which can range from annoying system delays to outright system crashes. Browser hijacker viruses are usually used by cyber-criminal nowadays and Yahoo000.net Redirect Virus is one of them. In addition, the term “virus” is also commonly used to refer to other types of malware do not have a reproductive ability. Typical examples are SOPA Virus, Trojan Horse Patched_c.MIS Virus, Worm:Win32/Donked.A Virus and Federal Computer Crime Unit Virus.
A worm is a program that multiplies itself but it does not infect the host. This means that a worm can carry out its purposes without resorting to a host program and it can be spread with or without being sent or shared by the computer user. This type of malware can infect entire computer networks giving rise to slow connection speeds. The most common way of spreading a worm is the use spam email. Take ILOVEYOU, a.k.a. LoveLetter as an example. This Love Letter worm was extremely widespread in 2000. It attacked tens of millions of Windows computers. The worm arrived in email inboxes on and after May 4, 2000 with the simple subject of “ILOVEYOU” and an attachment “LOVE-LETTER-FOR-YOU.TXT.vbs”. The final ‘vbs’ extension was hidden by default, leading unsuspecting users to think it was a mere text file. Upon opening the attachment, the worm sent a copy of itself to everyone in the Windows Address Book and with the user’s sender address. It also made a number of malicious changes to the user’s system. A more recently released worm is Worm:MSIL/Necast.D.
