Scanner detects all types of file-viruses:
 * Troians
 * Trivial viruses

Now scanner can detect 7380 viruses.

Why only 7380 ? ... Because now I have only 7466 viruses samples in 
my virus collection ...

 Comparision with other Anti-Viruses (speed tests)  
----------------------------------------------------------------------
I tested several anti-virus products on two sets of files :
 
 1. My collection of CLEAR FILES (3027 different software files )

 2. Files from MS-DOS 6.22 , some archiving utilities (PKZIP,ARJ,RAR,..)
     and files from Norton Commander 5.0 . Total 145 files .
     ( Files, that probably often persist on user hard drive )


Name of product              Set 1 (3027 files) I  Set 2 (145 files)

*) On small number of files from SET 1 this BETA version of Scanner works slow 
 (up to 10 sec on file) and this affects on result time . 
Now I am working on this problem , but the solution will be included 
 only in future versions of Scanner.

Also I test quality of detection of some complex viruses.
When I check detection on virus RDA.Fighter.7408, I see that McAfee VirusScan
can't detect RDA.Figter.7408 in half of the samples .Others detect all samples.
