so how can one make or create a computer virus?

IMO:
Here are the reasons:

1.) They Hate Micro$0ft
2.) They only do this for learning experience
3.) In my country IMO: Because we have lots of graduates every year and there are not enough jobs for them. A certain percent of computer graduates who doesnt have jobs. May just do this, because they just wanted to improve or test their skills.

so that never answered my question. how does one create a virus?? im curious..

ok, you must be knowledgable with the following:
Windows OS, You must know one of the following :

1.) Assembly or C, C++
2.) Windows Scripting
3.) And you must have a great dedication to read a lot of online documents regarding TCP/IP, RPC and some Internet and OS related stuff.

hmm interesting, please tell me more,lol. whats the easy way?lol

Its a longshot!

But If I were you do something more productive rather than learning to create a virus.

yeah, your right,lol
