DS.512.a

It’s a dangerous memory resident parasitic stealth virus. It installs itself in system memory without correction of system memory blocks, which can cause a system crash. Then the virus hooks INT 13h (for stealth routine), INT 21h (for infection routine) and hits \COMMAND.COM file. Then it writes itself into the middle of COM- and EXE-files that are executed. It infects some files incorrectly, they halt the system on execution. It contains the internal string: “DS”.
