Pande.1520
Description Pande.1520
It is a dangerous memory resident parasitic stealth virus. It writes itself to the end of COM and EXE files that are accessed. While installing memory resident the virus scans DOS kernel, patches it, hooks INT 21h and leaves its copy in UMB memory, if it is available. If several anti-viruses (F-PROT, TBAV) or utilities (ARJ, RAR, LHA, PKZIP, CHKDISK) are run, the virus disables its stealth routines. The virus has a bug and may halt the system.
The virus contains the text strings:
pandemonium by retch
