Threat Encyclopedia

Selected viruses, spyware, and other threats: sorted alphabetically

Solar

This is a family of viruses by author who calls himself Solar Designer. He claims that this is his first (and maybe also the last) attempt to create a virus. If this is true, his attempt is quite successful because these are some of the smallest non-overwriting EXE infectors. Common features of this virus family are: memory resistance (with body in INT table), protection against multiple infection, correct processing of “overlay” files and use of 286+ instructions. They all have in common also certain simplifications that decrease efficiency of infection. They differ in the level on which they treat work with the EXE header.
