Make a second version of MIRC that is striped to the basic things only and is not open to viruses

mIRC is not open to viruses. People may get them whilst using mIRC because they accept files from people that they don't know. But those same people also get viruses whilst using Instant Messaging programs. Heck, I could message those people on this webboard and get them to take a virus.

Those kind of people who accept files from people they don't know will always get viruses one way or another.

The scripting language is not dangerous, As long as you don't accept script files from people that you dont know. The scripting language is there for you to write your own scripts, for your own needs.

So "Make a second version of MIRC " is not nescassary, Because "People who keep getting infected" would still keep getting infected. Because it has nothing to do with mIRC, And it has everything to do with them.
