bah i can do this
my first task will be rewriting clamwin portable (open source free stuff), as a learning experience.
the computer guy at school recommended visualbasic to make software?
You don't use Visual Basic to write heavy duty software, maybe a database front end or some fluffy click here to make noise program. Let's put it this way, if you don't even know which language to pick to do this, how are you going to learn how every piece of the OS can be attacked, and have your software watch for it and block it?
Just out of curiousity I asked my father, who has been programming low level code for about 30 years now, how long it would take him to write an advanced program to hook into the OS without knowing the OS code beforehand. He said about 2 years for a basic start.
