Compressors / Packers

Compressors or Packers are legitimate compression utilities which will compress (make smaller) Windows® program files - .EXE files. In a similar way to using a popular file compression utility such as WinZip before e-mailing, compressors do the same for executable files. However, unlike WinZiped files, which require to be decompressed before loading, compressed executables run in their new state. Because of this, the executable will pass through any anti-virus scanning engine because the virus signature has been modified and the anti-virus software will not recognize it
