1260 is a computer virus developed by Mark Washburn in 1989. This virus used a form of polymorphic encryption in it's code which randomized the algorithm used by the virus but kept the core function of it intact. Polymorphic code does this by infecting files with an encrypted copy of itself, then varying it's signature by randomizing its decryption algorithm. Then it repeats. Hope this helped, here's some relevant info on the subject:

Are hydre polymorphic?
yes they exhibit polymorphism.. they have zooids and hydroids
How is polymorphic DNA used for identification purposes?
Polymorphic DNA is a stretch or multiple stretches of DNA that have high variability among individuals. Since the chance of DNA being different among these stretches in two different people, these pieces of DNA are commonly used for identification purposes.
What virus has RNA as its genetic material?
There are many viruses with RNA. Here are a few examples: Ebola virus, HIV, and the viruses causing measles, mumps, polio, rabies, rubella, and yellow fever. In the Baltimore classification of viruses, four of the seven major groups (classes III to VI) store their genetic information in RNA. For further information, look at the links below. technically hat is not true because RNA viruses don't kill.

What is the name of the polymorphic virus 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.
Do polymorphic viruses change depending on the program they encounter?
A polymorphic virus will more commonly change randomly every time it runs. It is easier to program it that way and it works equally well.See related link.
Which of the following classifications of viruses can change its own code to avoid detection?
A polymorphic virus is able to change its code to evade detection by antivirus software, making it difficult to analyze and detect.
What are types of hidden and active viruses?
Hidden viruses include rootkits, bootkits, and stealth viruses that hide their presence on a system to evade detection. Active viruses include file infectors, macro viruses, and polymorphic viruses that infect files or use different code patterns to avoid detection.
What type of computer programs did the Dark Avenger Mutation Engine promise to make more powerful?
Viruses. Dark Avenger created a Polymorphic (mutation) Engine which allowed viruses to duplicate themselves, each time modifying itself (mutating itself). This made it incredibly difficult for anti virus softwares to detect the virus, so much so that they needed to create a new technique in order to detect these Polymorphic (mutating) viruses.
What are polymorphic cells?
Polymorphic cells are cells that can change shape and adapt their structure to perform different functions. This ability allows them to fulfill various roles within the body and respond to different environmental conditions. Examples of polymorphic cells include immune cells like macrophages and white blood cells.
What is polymorphic regarding malware?
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 code was the first technique that posed a serious threat to virus scanners. Just like regular encrypted viruses, a polymorphic virus infects files with an encrypted copy of itself, which is decoded by a decryption module. In the case of polymorphic viruses, however, this decryption module is also modified on each infection. A well-written polymorphic virus therefore has no parts which remain identical between infections, making it very difficult to detect directly using signatures. Antivirus software can detect it by decrypting the viruses using an emulator, or by statistical pattern analysis of the encrypted virus body. To enable polymorphic code, the virus has to have a polymorphic engine (also called mutating engine or mutation engine) somewhere in its encrypted body. See Polymorphic code for technical detail on how such engines operate.[21] Some viruses employ polymorphic code in a way that constrains the mutation rate of the virus significantly. For example, a virus can be programmed to mutate only slightly over time, or it can be programmed to refrain from mutating when it infects a file on a computer that already contains copies of the virus. The advantage of using such slow polymorphic code is that it makes it more difficult for antivirus professionals to obtain representative samples of the virus, because bait files that are infected in one run will typically contain identical or similar samples of the virus. This will make it more likely that the detection by the virus scanner will be unreliable, and that some instances of the virus may be able to avoid detection.
