Actually, it is my understanding that LZEXE can be a harbor for viruses.  The 
reason is that a virus can be put into a program and then compressed.  Once the
program is compressed, I know of no virus checker that will find the virus.  So
I would recommend that the compressed exe files be uncompressed and then run
through a virus checker, and then recompressed.
