What type of virus was the famous Michealangelo virus?
The Michelangelo virus is a computer virus first discovered in April 1991 in New Zealand.[1] The virus was designed to infect DOS systems (but did not engage the operating system or make any OS calls; Michelangelo, like all boot sector viruses, basically operated at the BIOS level) and remained dormant until March 6, the birthday of Renaissance artist Michelangelo. There is no reference to the artist in the virus, and it is doubtful that the virus writer intended Michelangelo to be referenced to the virus. Michelangelo is a variant of the already endemic Stoned virus.On March 6, if the PC is an AT or a PS/2, the virus overwrites the first one hundred sectors of the hard disk with nulls. The virus assumes a geometry of 256 cylinders, 4 heads, 17 sectors per track. Although all the user's data would still be on the hard disk, it would be irretrievable for the average user.On hard disks, the virus moves the original master boot record to cylinder 0, head 0, sector 7.On floppy disks, if the disk is 360 KB, the virus moves the original boot sector to cylinder 0, head 1, sector 3.On other disks, the virus moves the original boot sector to cylinder 0, head 1, sector 14.This is the last directory of the 1.2 MB disks.This is the second-to-last directory of the 1.44 MB disks.The directory does not exist on 720 KB disks.Although designed to infect DOS systems, the virus can easily disrupt other operating systems installed on the system since, like many viruses, the Michelangelo infects the master boot record of ahard drive. Once a system became infected, any floppy disk inserted into the system (and written to; in 1992 a PC system could not detect that a floppy had been inserted, so the virus could not infect the floppy until some access to the disk is made) becomes immediately infected as well. And because the virus spends most of its time dormant, activating only on March 6, it is conceivable that an infected computer could go for years without detection - as long as it wasn't booted on that date after being infected.The virus first came to widespread international attention in January 1992, when it was revealed that a few computer and software manufacturers had accidentally shipped products, for example Intel'sLANSpool print server, infected with the virus. Although the infected machines numbered only in the hundreds, the resulting publicity spiraled into "expert" claims of thousands or even millions of computers infected by Michelangelo. However, on March 6, 1992, only 10,000 to 20,000 cases of data loss were reported. The news media lost interest, and the virus was quickly forgotten. Despite the scenario given above, in which an infected computer could evade detection for years, by 1997 no cases were being reported in the wild.
Identify five types of client computer?
There are 6 types of viruses. They are as follows: 1. The Boot Virus. A virus that infects the MBR record on your hard drive. If you still use floppy disks, then it can affect those as well. 2. Program viruses: These infect executable program files, such as those with extensions like .BIN, .COM, .EXE, .OVL, .DRV (driver) and .SYS (device driver). 3. Multipartite viruses: A hybrid of Boot and Program viruses. They infect program files and when the infected program is executed, these viruses infect the boot record. When you boot the computer next time the virus from the boot record loads in memory and then starts infecting other program files on disk. 4. Stealth viruses: These viruses use certain techniques to avoid detection. They may either redirect the disk head to read another sector instead of the one in which they reside or they may alter the reading of the infected file's size shown in the directory listing. 5. Polymorphic viruses: A virus that can encrypt its code in different ways so that it appears differently in each infection. 6. Macro Viruses: A macro virus is a new type of computer virus that infects the macros within a document or template. When you open a word processing or spreadsheet document, the macro virus is activated and it infects the Normal template (Normal.dot)-a general purpose file that stores default document formatting settings. Every document you open refers to the Normal template, and hence gets infected with the macro virus. Since this virus attaches itself to documents, the infection can spread if such documents are opened on other computers. Source: rishab v on Yahoo Answers.
What is a computer attack?
A computer attack is basically either when a hacker is on your computer doing things that you can do. Or it can be a Virus
What are ways for malware authors to get around antivirus engines?
Some methods they use are: Stealth mode - the virus intercepts requests from the anti-virus program and returns the information the anti-virus program would expect from a non-infected program. Self-modification or mutation - the program changes its code slightly with each infection to make it harder for anti-virus software to create a "signature" for the virus Encryption of the payload - this may obfuscate the actual virus, especially if a different encryption key is used each time. The code still has to have a decrypting function attached to allow the virus to unpack and execute. Polymorphic viruses - this is sort of a combination of the encryption and mutation tactics. The virus payload is encrypted and the decrypting function modifies itsself with each infection to make it very tough to create a signature for the virus.
Is zeon a computer virus?
Yes and no. No because an anti virus and yes because a lot of virus definitions are reported in virus killers before the virus is made. So in short no it's a Antivirus that probably make their own virus's.
What is a boot-sector virus?
multipartite virus
Which virus uses both boot-sector and executable functions?
A virus that uses both boot-sector and executable functions is a multipartite virus. This type of virus attacks a variety of platforms, and continually re-infects each platform until it is removed.
Kinds of virus?
There are about nine types of computer viruses. They include the boot sector virus. the browser hijacker, direct action virus, file infector virus, macro virus, Multipartite Virus, Polymorphic Virus, Resident Virus, and Web Scripting Virus.
What are 7 types of computer virus?

What kind of virus is designed to infect multiple file types in an effort to fool antivirus software?
A multipartite virus is designed to infect multiple file types in an effort to fool antivirus software
Virus can hide in either of two boot areas of a hard drive?
boot sector virus
What is mutipartite?
I do not know what mutipartite is; however, I think you mean Multipartite virus? Multipartite virus will target your bootsector and any executable it can find. A word of caution: when removing this virus, it is imperitave that you remove all of its components, otherwise it will continue to ravish your machine. (If this is not what the question is asking for please delete my text when you answer).
What is the worst multipartite computer virus can do?
Just as much as any other virus can do. A multipartite virus is just a virus that works on multiple different platforms (Windows, Linux etc.). Probably the worst would be to publish all your personal information on the Internet, overwrite it several times on your local hard disk, empty your printers cartridge and flash your BIOS with garbage. Usually viruses are a lot less intrusive however. http://en.wikipedia.org/wiki/Multipartite_virus
What is system sector boot virus?
A boot sector virus is a computer virus that puts itself in the boot sector of a computer. The boot sector is the partition on the disk drive that contains all of the programs and files necessary for the computer to start up. This ensures that the virus will be executed once the computer is turned on.
What are the characterisics of a virus?
(1) file virus (2) boot sector virus
What Kind of computer virus?
Here you go... Browser Hijacker, File Infector, Macro Virus, Polymorphic Virus, Multipartite Virus, Direct Action Virus, Boot Sector Virus, Web Scripting Virus, Memory Resident Virus, FAT Virus.
