Worm: questi malware non hanno bisogno di infettare altri file per diffondersi, perché modificano il sistema operativo della macchina ospite in modo da essere eseguiti automaticamente e tentare di replicarsi sfruttando per lo più Internet.
Sono malware quando vengono utilizzati in modo truffaldino, modificando il numero telefonico chiamato dalla connessione predefinita con uno a tariffazione speciale, allo scopo di trarne illecito profitto all'insaputa dell'utente.
Si noti che un malware è caratterizzato dall'intento doloso del suo creatore, dunque non rientrano nella definizione data i programmi contenenti bug, che costituiscono la normalità anche quando si sia osservata la massima diligenza nello sviluppo di un software.

Malware programs are usually poorly-programmed and can cause your computer to become unbearably slow and unstable in addition to all the other havoc they wreak.
However, some especially virulent malware that malware scanners may miss will be removed by anti-virus programs, so it is generally a good idea to run a virus scan as well.
Malware toolbars almost always include characteristics of the other malware categories, which is usually what gets it classified as malware.

 Are You Infected? Detecting Malware Infection
However, if you find out that certain malware is indeed on your system after verifying with the AV vendors' reports, you can terminate the malware in memory and proceed to find out what other things it has added or modified on your system.
For a malware, it is rather important for it to be executed every time and to advocate its aim to be memory resident.
A malware can also try to accomplish this by adding links to itself in the autoexec.bat or config.sys, which are configuration files used by DOS and even Windows systems on its basic start up scheme.

Malware that exhibits this characteristic uses encryption as a defense mechanism to defend itself and is able to change the encryption routine only a fixed number of times (usually a small number).
Malware of this type uses encryption as a defense mechanism to change itself to avoid detection, typically by encrypting the malware itself with an encryption routine, and then providing a different decryption key for each mutation.

 May 2002 - Trojans - Combating Nonviral Malware - Trojans, sniffers and spyware, oh my!   (Site not responding. Last check: )
The formal definition of malware is "malicious software." The only safe assumption is to treat all unwanted code as "malicious." While viruses and worms are the most visible forms of malware, "unwanted code" describes a broad range of software that potentially violates an organization's security policy.
One form of malware that's often overlooked is the logic bomb, a program whose only purpose is to destroy data and applications.
Some nonviral malware can be detected using heuristics, a psychological term that means "rule of thumb." In the context of IT security, heuristics refers to the ability to infer that a particular binary might be hostile based on typical sequences of operation within the object code.

While you take notes during the process of analyzing malware that was used to harm your organization, keep in mind that these notes could be used as evidence in a court of law, even if you don't want them to be.

 MIT IS&T: Dealing with Spyware and Other Malware
Malware programs can range from being simple annoyances (pop-up advertising) to causing serious computer invasion and damage (e.g., stealing passwords or introducing worms and viruses).
To prevent malware from being installed on your system, avoid using software that relies on advertising as their means of support, i.e., sponsored mode.
Be cautious about "free" or peer-to-peer software since they usually recoup their costs by being paid to bundle malware into their applications that track users web-browsing habits and send the information to marketers or other third parties.

When thinking about malware predictions for the coming year, my chief concern was the emergence of something that combined viral and worm properties, burrowed through published security vulnerabilities and appeared before I could publish a warning.
The biggest, mostly likely malware threat to emerge in the next six months is a variant of Nimda.
Given that Nimda was internally listed as v0.5, and given that the original worm didn't exploit all the known vulnerabilities, it's more than reasonable to expect a v1.0, or higher, seeded on some of the leftover Code Red-compromised PCs still out there, and set to all launch within minutes of each other.

The term rootkit is used to describe the mechanisms and techniques whereby malware, including viruses, spyware, and trojans, attempt to hide their presence from spyware blockers, antivirus, and system management utilities.
There are several rootkit classifications depending on whether the malware survives reboot and whether it executes in user mode or kernel mode.
Because such malware contain code that must be executed automatically each system start or when a user logs in, they must store code in a persistent store, such as the Registry or file system, and configure a method by which the code executes without user intervention.
