About trojan, spyware rootkits

Hello, I do not need help. I did not know where to post it. I need some information about how Trojan, spyware or rootkits work. I need to know how they work. When someone infected your computer with one of these and if I had access to this person's computer, what must I be looking for? Is there a program that controls them, or he doesn't need one? If he infected my computer can he access it from any other computer? Can this person know the windows login password and/or the bios password with these infections? Can I have a elaborate answer for each one of these infections? Thanks.

 

Hi bras33,

There are books full of information on what you are looking for.

 

Well I don't have those books. I tried online with no success

 

Try Barnes and Nobles. There are some books there with 400+ pages on what you are looking for.

 

Thanks

 

You're welcome.
