Encrypted Virus

Similar to popular methods of cryptography, an encrypted virus scrambles it’s programming code to make it difficult to crack. One of the most common forms of this infection is identified by the Polymorphic Virus. Aside from containing an encryption that hides it from detection, it also decrypts itself to spread the virus throughout the system. This type of encrypted virus is difficult for anti-virus software to detect because the infection generates a completely different decryption pattern every time it corrupts an executable file. It is important for a user to make sure that their security scanning application is configured to check ALL FILES, even those that are archived and encrypted. When the option is available, it is best to use a security tool that enables the installation of configurations for ALL USERS instead of CURRENT user. This option will use advanced methods of decryption even when an encrypted virus returns an error message on the scanner.
