Anti Anti-Virus Viruses

Anti anti-virus viruses put forth their energy and efforts into targeting anti-virus programs.  These are also called retro viruses.  

Anti anti-virus viruses try to keep the user from detecting them by corrupting the anti-virus software.  In attacking anti-virus software, they will try to delete or change the anti-virus programs and data files so that they do not function properly.  

Retro viruses sometimes try to avoid corrupting anti-virus software while in the infection phase.  They do this because, if the anti-virus software is not working properly, the user will attempt to fix it.  This would make it difficult for the virus to continue spreading

Examples of anti anti-virus viruses:  Goldbug, Tequila, Varicella, and Tremor
