Comparison Of Computer Viruses
The compilation of a unified list of computer viruses is made difficult because of naming. To aid the fight against computer viruses and other types of malicious software, many security advisory organizations and developers of anti-virus software compile and publish lists of viruses. When a new virus appears, the rush begins to identify and understand it as well as develop appropriate counter-measures to stop its propagation. Along the way, a name is attached to the virus. As the developers of anti-virus software compete partly based on how quickly they react to the new threat, they usually study and name the viruses independently. By the time the virus is identified, many names denote the same virus. Another source of ambiguity in names is that sometimes a virus initially identified as a completely new virus is found to be a variation of an earlier known virus, in which cases, it is often renamed. For example, the second variation of the Sobig worm was initially called "Palyh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Computer Viruses
A computer virus is a type of computer program that, when executed, replicates itself by modifying other computer programs and inserting its own code. If this replication succeeds, the affected areas are then said to be "infected" with a computer virus, a metaphor derived from biological viruses. Computer viruses generally require a host program. The virus writes its own code into the host program. When the program runs, the written virus program is executed first, causing infection and damage. A computer worm does not need a host program, as it is an independent program or code chunk. Therefore, it is not restricted by the host program, but can run independently and actively carry out attacks. Virus writers use social engineering deceptions and exploit detailed knowledge of security vulnerabilities to initially infect systems and to spread the virus. Viruses use complex anti-detection/stealth strategies to evade antivirus software. Motives for creating viruses can inclu ...

AI (computer Virus)
AI is a computer virus which infects executable files. The virus is loaded into memory by running an infected file and then modifies the computer's run time operation and corrupts program and overlay files. It doesn't seem to work with all executables but does reliably infect standard DOS files. AI adds useless bytes The byte is a unit of digital information that most commonly consists of eight bits. Historically, the byte was the number of bits used to encode a single character of text in a computer and for this reason it is the smallest addressable uni ... to the end of infected files References External links Computer Viruses (A) by Probert Encyclopedia by Symantec DOS file viruses {{malware-stub ...

AntiCMOS (computer Virus)
AntiCMOS is a boot virus. Its first discovery was at Lenart, Slovenia, which led to its alias of Lenart. It was isolated in Hong Kong several times at the beginning of 1994, but did not become common until it spread to North America in the Spring of 1995. AntiCMOS is a fairly standard boot virus, and is primarily notable for being one of the few DOS DOS is shorthand for the MS-DOS and IBM PC DOS family of operating systems. DOS may also refer to: Computing * Data over signalling (DoS), multiplexing data onto a signalling channel * Denial-of-service attack (DoS), an attack on a communicat ... viruses to remain in the wild as of 2020. AntiCMOS is so named because it has the intended effect of erasing all CMOS information. This does not occur because of a bug in the virus code. This is true of all AntiCMOS variants that have appeared in the wild. The payload date of December 1993 and the obsolete nature of these variants makes it very unlikely that AntiCMOS's payload ...

ANTI (computer Virus)
ANTI is a computer virus affecting Apple Macintosh computers running classic Mac OS versions up to System 6. It was the first Macintosh virus not to create additional resources within infected files; instead, it patches existing CODE resources.Eugene H. Spafford, Kathleen A. Heaphy and David J. Ferbrache,A Computer Virus Primer, 28 November 1989, p. 36. ''Computer Science Technical Reports'' Paper 795Peter J Denning (editor), ''Computers Under Attack'', ACM Press, 1990, p. 350 The most commonly encountered strains of ANTI have only subtle effects, and thus can exist and spread indefinitely without being noticed until an antivirus application is run.Bruce Schneier, Protect Your Macintosh', Peachpit Press, 1994, pp. 124-125 Due to a bug in the virus, it cannot spread if MultiFinder is running, which prevents it from infecting System 7 and later versions of Mac OS as well as System 5 and 6 running MultiFinder.David HarleyViruses and the Macintosh/ref>Paul Baccas (editor), OS X Exp ...

Sneek
Sneek (; fy, Snits) is a city southwest of Leeuwarden and the seat of the former municipality of Sneek in the province of Friesland, Netherlands. As of 2011 it is the seat of the municipality of Súdwest-Fryslân (Southwest Friesland). The city had approximately 33,855 inhabitants in January 2017. Sneek is situated in Southwest Friesland, close to the Sneekermeer, and is well known for its canals, the Waterpoort (''Watergate'', the symbol of the city), and watersports (hosting the annual Sneekweek, the largest sailing event on inland European waterways). Sneek is one of the '' Friese elf steden'' ("Eleven cities of Friesland"). The city is very important in the southwestern part of Friesland (called the Zuidwesthoek, or ''Southwest Corner''). History History Sneek was founded in the 10th century as ''Chud'' on a sandy peninsula at the crossing site of a dike with an important waterway (called the ''Magna Fossa'' in old documents). This waterway was dug when ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
VBScript
VBScript (''"Microsoft Visual Basic Scripting Edition"'') is an Active Scripting language developed by Microsoft that is modeled on Visual Basic. It allows Microsoft Windows system administrators to generate powerful tools for managing computers without error handling and with subroutines and other advanced programming constructs. It can give the user complete control over many aspects of their computing environment. VBScript uses the Component Object Model to access elements of the environment within which it is running; for example, the FileSystemObject (FSO) is used to create, read, update and delete files. VBScript has been installed by default in every desktop release of Microsoft Windows since Windows 98; in Windows Server since Windows NT 4.0 Option Pack; and optionally with Windows CE (depending on the device it is installed on). A VBScript script must be executed within a host environment, of which there are several provided with Microsoft Windows, including: Windows ...

E-Mail
Electronic mail (email or e-mail) is a method of exchanging messages ("mail") between people using electronic devices. Email was thus conceived as the electronic ( digital) version of, or counterpart to, mail, at a time when "mail" meant only physical mail (hence '' e- + mail''). Email later became a ubiquitous (very widely used) communication medium, to the point that in current use, an email address is often treated as a basic and necessary part of many processes in business, commerce, government, education, entertainment, and other spheres of daily life in most countries. ''Email'' is the medium, and each message sent therewith is also called an ''email.'' The term is a mass noun. Email operates across computer networks, primarily the Internet, and also local area networks. Today's email systems are based on a store-and-forward model. Email servers accept, forward, deliver, and store messages. Neither the users nor their computers are required to be online simult ...

Anna Kournikova (computer Virus)
Anna Kournikova (named Vbs.OnTheFly by its author, and also known as VBS/SST and VBS_Kalamar) was a computer virus that spread worldwide on the Internet in February 2001. The virus program was contained in an email attachment, purportedly an image of tennis player Anna Kournikova. Background The virus was created by 20-year-old Dutch student Jan de Wit, who used the pseudonym "OnTheFly", on 11 February 2001. It was designed to trick email users into clicking to open an email attachment ostensibly appearing to be an image of the professional tennis player Anna Kournikova, but instead hiding a malicious program. The virus arrived in an email with the subject line "Here you have, ;0)" and an attached file entitled AnnaKournikova.jpg.vbs. When opened in Microsoft Outlook, the file did not display a picture of Kournikova, but launched a viral VBScript program that forwarded itself to all contacts in the victim's address book. De Wit created Anna Kournikova in a matter of hours using a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ambulance (computer Virus)
Ambulance or Ambulance Car is a computer virus that infected computers running a DOS operating system in June 1990. It was discovered in Germany. Description Ambulance does not become memory resident. It infects only one .COM file in any given directory, but not the first one. Thus, there must be at least two .COM files in a directory for it to spread. When an infected file is executed, an ASCII art ambulance can be seen moving across the screen, a siren starts to sound, and it displays an alert message such as: BOOM! It is not a deliberately destructive virus; it simply spreads itself around and shows off its payload once in a while. In certain iterations of the virus, the ambulance will only appear once per boot-up. Variants These are just some of many variants detected: * Ambulance Car-B * RedX-Any * Ambulance.793 * Ambulance.793.A * Ambulance.795 * Ambulance.796A See also *Comparison of computer viruses The compilation of a unified list of computer viruses is made ...

Alcon (computer Virus)
Alcon, or RSY (which is more or less as commonly used of a name as Alcon), is a computer virus that was discovered to be spreading in Europe in 1997. It is a boot virus. Infection Alcon is a standard boot sector virus that spreads via floppies. Instead of the MBR, it infects the DBR, making some antivirus programs miss it. Symptoms Alcon contains no notable symptoms beyond one extremely damaging one, which is overwriting random information. Assuming that the overwrites are subtle, this may result in significant compounding data over time, as Alcon is a slow damager. Alcon contains the text "R.SY". Prevalence Alcon was listed as being spreading by the WildLisfrom April 1998 to July 1999. F-Secure lists it as having been common in Europe throughout 1997. Like most boot viruses, it is near extinct, although it was certainly in the last wave of boot viruses, so cases involving Alcon may be false positives A false positive is an error in binary classification in which a test ...
