reformat the hard drive and reload the operating system. then restore from a backup date previous to the date of infection. all data stored between the backup date and the reformat date will be lost.
polymorphic
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.
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.
It is a virus that stops your computer at startup. They are very effective because you cant turn on your computer to get rid of it.
Run an anti virus programme that'll sort it . . or stop looking at porn!!
polymorphic
There have been several polymorphic virus outbreaks. In 1991, the Tequila virus was the cause.
A polymorphic virus is a virus that can "shape-shift" from every infection, making it extremely hard for antiviruses using virus signatures to detect viruses to detect it.
A polymorphic virus is an advanced type of computer virus. It is similar to an encrypted virus in that it consists of an encrypted copy of the virus and a small decrypting module but every time a polymorphic virus infects a file it encrypts itself differently and rewrites the decrypting module. A well written polymorphic virus therefore has no parts that remain the same between infections making it hard for anti-virus software to detect using virus signatures.
the answer Tequila is the name of the outbreak in 1991
The name is Polymorphicalayyelas virus
polymorphic
A polymorphic virus not only replicates itself by creating multiple files of itself, but it also changes it's digital signature every time it replicates.

polymorphic virus
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.
it is called polymorphic virus
