Sality is a family of polymorphic file infectors, which target Windows executable files with the extensions .EXE or .SCR. [1] Sality utilizes polymorphic and entry-point obscuring (EPO) techniques to infect files using the following methods: not changing the entry point address of the host, and replacing the original host code at the entry point of the executable with a variable stub to ...
The first known polymorphic virus was written by Mark Washburn. The virus, called 1260, was written in 1990. A better-known polymorphic virus was created in 1992 by the hacker Dark Avenger as a means of avoiding pattern recognition from antivirus software. A common and very virulent polymorphic virus is the file infecter Virut.
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.
Polymorphic virus which infects systems by inserting fragments of its code randomly into executable files.

After the file becomes resident in the system memory below the 640K DOS boundary, system slow-down occurs as a result of the virus' polymorphic code. [citation needed] Symptoms include video flicker and output to screen appearing very slowly. Files may seem to "hang" even though they will eventually execute correctly.
Christmas can already be stressful enough. The last thing you want is anxiety about your pet's health. Here's how to cat-proof your home this holiday.
Michael Kors has a bit of both; you can still enjoy the Black Friday deals of 25% off sale items and up to 70% off other items sitewide, but for even more savings, use code CYBER15 and get 15% off ...
1260, or V2PX, [1] [2] was a polymorphic computer virus written in 1989 by Mark Washburn. Derived from Ralf Burger's publication of the disassembled Vienna Virus source code, the 1260 added a cipher and varied its signature by randomizing its decryption algorithm. Both the 1260 and Vienna infect .COM files in the current or PATH directories ...
