However, one of the screen shots (the middle one) shows a tool that says 'Mass Visit Website'. So it basically allows you to do DoS attacks? That's illegal right there.
So are alot of network utilities. It all depends on your intent on using it. Alot of pen tests rely on such tools and have legitament reasons for use. Remember 'SATAN' (Systems Analysts Tool for Analyzing Networks - At least I think that's what it means). That was the 'devils' program since it basicly allowed for a blackhatter to do pretty much what he wanted to a network. But it was originally developed for research and developement for network security.
Besides when has brushing on the other side of the law when it comes to computers and software ever stopped us
before?
EDIT: maybe you should stay away, unless this is a false positive just due to the nature of the programs used, I got a Virus Warning on a file that was installed.
"ProgramFiles\Net Tools\LANTalkerServer.exe
Trojan horse BackDoor.Generic8.TYM"
Now from the look of that filename, it is probably considered a virus by the scanner because of what it does. If anyone can scan this with another scanner and post your results, that would be informative.
Upon further inspection (and throwing caution to the wind) I ran it and it actually is a VERY useful tool. I can't count how many situations where this tool can save alot of work.
