Net Tool 5.0.70
Net Tools is a suite of network utilities containing network monitoring software and security software. 
When I first installed the program, I was amazed by the large diversity of tools included. Actually, in case I’d like to write an exhaustive review for this suite, I’d have to review all of it’s tools, which I won’t do. This is because there are 136 Internet tools (scanners, sniffers, traffic monitors, FTP client, etc), 35 file tools (comparison, steganography, encryption), 19 miscellaneous tools, 14 system tools. This means that you can use this program for pretty much everything. The good news is that the programs work, although some may be a little bit out of date (for example, an encryption tool).
The is simple and has a nice design. The program menu is customizable, so that you can create a list of programs you need the most or of common use.
