Bat2Exec
Description Bat2Exec
Bat2Exec is a dangerous not memory resident overwriting virus. It searches for .COM- and .EXE-files and overwrites them. The virus code is of EXE-format, but the virus source code is the BAT-file with the commands such as:
FOR %%i IN (*.com) DO copy %0 %%i > nul
FOR %%i IN (*.exe) DO copy %0 %%i > nul
That source BAT-file was converted to EXE-file with BAT2EXEC utility, and then packed with PRO-PACK compression utility.
The virus (EXE-file) contains the internal text string (after unpacking):
