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.

∙ 11y agoPolymorphic 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.

Which virus can change its own code?
polymorphic
Is E underscore FARNBZP dot EXE a malware?
it is a malware. go to www.prevx.com to download a scanner.
What scanning detects malware by comparing a file content with known malware signatures in a signature database?
Um, signature.
What is difference between heuristic detection and sigbature scanning?
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.
What are some of the motivations behind malware and security breaches?
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.
