F-Prot 2.19 detects this virus.
SCAN 226 detects variant 2824 as 2803 and incorrectly disinfects the 
files. Disinfected files become unusable. Scan removes the virus but 
does not fix the pointer to the start of the .EXE program so the first 
step jumps to where the virus used to be causing a crash or worse.
