To change and restructure in multiple ways, so as to show a different signature and thus avoid detection.
For instance, if you link-edit a large group of object modules, their order is not 100% critical as long as they're accessed at the proper entry point. So malware that changes the hash and the signature of the executable this way as part of its operation can be said to be polymorphic.
Polymorphic and metamorphic viruses are both self-replicating and "shape-shifting" malware. When they infect a computer, they replicate as normal. The only difference between the copies is that they are not the same. When a polymorphic/metamorphic virus replicates, they encrypt themselves and slightly change their code as to confuse antivirus software. The decryption key is built into the virus so that they can decrypt and deliver the payload to the infected computer. The difference between polymorphic and metamorphic viruses is the that metamorphic rewrites with each iteration so that each succeeding version of the virus is a little bit different from the preceeding one. Polymorphic viruses also make changes to its code to avoid detection, but one part remains the same as the iteration, which makes the virus a little bit easier to identify. So in conclusion, metamorphic viruses are more complex than polymorphic viruses because they can encrypt and adapt better.

it is a malware. go to www.prevx.com to download a scanner.
Um, signature.
Heuristic detection looks for the characteristics of viruses and malware, while signature scanning looks for specific files known to be malware. In other words, heuristic detection can find recently created malware on a system, because it "acts" like other malware. Signature scanning looks at a list of known malware file names, and then sees if there are any of them on the computer.
The motivation behind malware is varied. Some malware is intended to be a relatively harmless prank or mildly annoying vandalism. Other malware is created to distribute political messages or to disrupt operations at specific companies. In an increasing number of cases, the motivation is monetary gain.

Polymorphic Programming Language was created in 1969.
A polymorphic virus is a type of malware that can change its code to avoid detection by antivirus software. It does this by encrypting or obfuscating its code in a way that it appears different each time it infects a new system. This makes it difficult for traditional signature-based detection methods to identify and remove the virus.
Polymorphic simple sequence repeats database was created in 2010.
Yes. Shapeshifters are polymorphic because they can change into any form they want to.
There have been several polymorphic virus outbreaks. In 1991, the Tequila virus was the cause.
Polymorphous.
the answer Tequila is the name of the outbreak in 1991
The polymorphic virus in 1991 was called the Tequila virus. It was one of the first viruses to utilize polymorphic code to change its appearance with each infection, making it harder to detect and remove.
