Also Known As:: Tequila (2)
Type:: Virus

The Tequila virus is an advanced memory-resident polymorphic virus, which uses several techniques to hide itself from the user. The virus body is encrypted and the virus changes itself from one infection to the next. Also, this virus uses both read stealthing and size stealthing, which means that an infected area’s size change will not be noticed during the DIR command or when a disk editing program is being used.
