MutInt Family
Description MutInt Family
These are dangerous memory resident encrypted parasitic viruses. They hook INT 21h and write themselves to the end of COM files that are executed. Sometimes these viruses infect the files incorrectly, these files halt the computer being executed.
While infecting the viruses encrypt their bodies with new method: they search for INT 21h (CD21h) opcodes in their codes, and replace them with opcode CDxxh, where 'xx' is a random selected byte. While executing the viruses replace these CDxxh back to CD21h.
These infectors contain the text string:
