Question: Which Is Not A Virus Category?

Is malware that tries to convince you that your computer is infected with a virus?

ScarewareScareware is part of a class of malicious software that includes rogue security software, ransomware and other scam software that tricks users into believing their computer is infected with a virus, then suggests that they download and pay for fake antivirus software to remove it..

Which type of virus was the famous Michelangelo virus?

Boot sector virusesMichelangelo is classified as a boot sector virus, a type of virus that infects the startup sectors of storage devices—usually the boot sector of a floppy disk or the master boot record (MBR) of a hard disk. Boot sector viruses are primarily spread through physical media such as floppy disks or USB drives.

What is a virus that is triggered on a certain date?

Time bombs are viruses that are triggered by the passage of time or on a certain date. Software that is inherently malicious, such as viruses and worms, often contain logic bombs that execute a certain payload at a pre-defined time or when some other condition is met.

What was the first virus?

Two scientists contributed to the discovery of the first virus, Tobacco mosaic virus. Ivanoski reported in 1892 that extracts from infected leaves were still infectious after filtration through a Chamberland filter-candle. Bacteria are retained by such filters, a new world was discovered: filterable pathogens.

Who is the father of virus?

Martinus BeijerinckMartinus Beijerinck is often called the Father of Virology.

Where did the first virus come from?

Virus-first hypothesis: Viruses evolved from complex molecules of protein and nucleic acid before cells first appeared on earth. By this hypothesis, viruses contributed to the rise of cellular life. This is supported by the idea that all viral genomes encode proteins that do not have cellular homologs.

Which of the following is the first step in boot process?

What is the first step in the boot process? – The BIOS loads the operating system into RAM. – The BIOS makes sure that all your computer’s peripheral devices are attached and working. – The BIOS verifies your login name and password.

What is a keygen quizlet?

What does a keygen do? Creates software registration numbers. … You can rent or lease the software. An encryption ______ is a set of steps that converts readable text into unreadable text.

70 yearsCopyright protection generally lasts for 70 years after the death of the author. If the work was a “work for hire”, then copyright persists for 120 years after creation or 95 years after publication, whichever is shorter. For works created before 1978, the copyright duration rules are complicated.

What was the name of the polymorphic virus outbreak in 1991?

The first polymorphic virus called the Chameleon was developed. 1991- The Chameleon virus is released and also becomes known as Tequila.

What was the very first virus?

Answer: Creeper, named for a character on the “Scooby Doo” cartoon show, is generally recognized at the first computer virus. It was written in 1971 by Bob Thomas of BBN Technologies and spread through DEC PDP-10 computers on ARPAnet, displaying the message, “I’m the creeper, catch me if you can!”

What was the first Trojan virus?

ANIMALCalled ANIMAL, the first Trojan (although there is some debate as to whether this was a Trojan, or simply another virus) was developed by computer programmer John Walker in 1975, according to Fourmilab.

Are viruses living?

Viruses are not living things. Viruses are complicated assemblies of molecules, including proteins, nucleic acids, lipids, and carbohydrates, but on their own they can do nothing until they enter a living cell. Without cells, viruses would not be able to multiply. Therefore, viruses are not living things.

What virus can change its own code?

metamorphic virusA metamorphic virus is one that can transform based on the ability to translate, edit and rewrite its own code. It is considered the most infectious computer virus, and it can do serious damage to a system if it isn’t detected quickly.

Is the portion of virus code that is unique?

A virus signature is a portion of virus code that is unique to a particular computer virus. Currently, there are no antivirus programs for mobile devices. An encryption virus replicates itself onto a hard drive’s master book record.

Which of the following is not a computer virus?

2. Which of the following is not a type of virus? Explanation: Types of viruses are System or Boot Sector Virus, Direct Action Virus, Resident Virus, Multipartite Virus, Polymorphic Virus, Overwrite Virus, Space-filler Virus, File infectors, Macro Virus, Rootkit virus. Trojan does not come under types of virus.

Do computer viruses mutate?

Computer viruses are not so different from other viruses. … And the way biological viruses mutate and evolve for survival, the makers of so-called malware must keep updating their “products” in order to escape antivirus software. But a new innovation could make it much more difficult to beat computer viruses.

What is a polymorphic virus in computing?

Polymorphic viruses are complex file infectors that can create modified versions of itself to avoid detection yet retain the same basic routines after every infection. To vary their physical file makeup during each infection, polymorphic viruses encrypt their codes and use different encryption keys every time.

What is a virus signature?

A unique string of bits, or the binary pattern, of a virus. The virus signature is like a fingerprint in that it can be used to detect and identify specific viruses. Anti-virus software uses the virus signature to scan for the presence of malicious code.

Who discovered virus?

In 1892, Dmitri Ivanovsky used one of these filters to show that sap from a diseased tobacco plant remained infectious to healthy tobacco plants despite having been filtered. Martinus Beijerinck called the filtered, infectious substance a “virus” and this discovery is considered to be the beginning of virology.

What is the difference between polymorphic and metamorphic malware?

A polymorphic virus decrypts its code, runs that code, and then when propagating itself encrypts the decrypted code with a different key. … A metamorphic virus simply runs its code and then when propagating itself mutates its code into different but functionally identical code.
