Koder.1024
Description Koder.1024
This is a dangerous memory resident partly encrypted parasitic virus. It hooks INT 21h, and writes itself to the end of EXE files that are executed. While opening an infected file, or while accessing to an infected file with FindFirst/Next DOS functions, the virus decreases the file length. Starting in September, the virus corrupts the CMOS check-sum field. The virus contains the text string:
KODER(96) WROCLAW
Check other viruses! Be aware! Use Antiviral Software
Csl.381
Description Csl.381
These are memory resident harmless (except "Csl.517") viruses. They copy themselves into the Interrupt Vector Table, hook INT 21h and infect by standard way COM-files which are loaded into the memory. "Csl.517" erases some bytes of CMOS. These viruses contain the text strings:
"Csl.381" - "26.07.91.Pre-released Microelephant by CSL";
"Csl.457" - "Microelephant V5 by CSL";
"Csl.517" - "Microelephant V4 by CSL".
CSSR.528
Description CSSR.528
CSSR.528 is harmless and not memory resident. By standard way it infects COM-files in the current directory. If one other virus (except stealth viruses) writes itself into the file infected by the "CSSR- 528", the latest will display the message: "Warning : File is damaged by virus !!!"
