Lamerman
Description Lamerman
It is a very dangerous memory resident multipartite virus. It infects the MBR of the hard drive and overwrites EXE files that are created or copied, i.e. the virus does not affect existing EXE files but newly created/modified files only.
When an infected file is executed the virus affects the MBR and halts the computer, while infecting the virus fools the BIOS virus protection by a simple keyboard trick. On rebooting the virus stays memory resident, hooks INT 13h and overwrites EXE files on writing to them.
The virus contains the text string:
Lamerman .01
LamersSuprise.1282
Description LamersSuprise.1282

---Oh No!, All your files are as good as dead, Data files manipulated
(only slightly) and executables infected with a BIG FAT VIRUS.--YOU
