Trojans AKA RATs (remote administraion tools) are pretty cool tools which you can use to gain access to a remote PC. You can do lots of things to the remote PC you are controlling you can open/close cd drive, remote shell(Command line), Screen/cam campture, Passwords, Key logger, download/upload files, execute+delete files Etc.

To access a remote PC Via RATs you must execute a Server (trojan) on the remote PC Either by sending via Email or MSN etc

To access a Remote PC you must first build your server which when executed on the remote PC will connect to your PC this is called Reverse connection where you can gain control of PCs behind Routers and Networks.

When building your server you will be asked to enter your DNS/Static IP so the remote PC can connect to your PC through a Port of your choice

Using these tools does NOT mean you are a hacker because it requires no skill and is easily detected by Anti-viruses (even though you can buy a Undetectable trojans)

Unfortunately RATs have fallen into the hands of immature people who send trojans to their friends and format their drives for no reason at all.

Programmers Often spend alot of time Building these Tools and most dont get enough respect for it.

So be careful what you download it could be a trojan and a immature noob could steal your data and your passwords
Noob: Hey, accept this its a well good game
Guy: wtf this makes my PC slow
Noob: HAHAHAHH GIMME UR HOTMAIL PASSWORD OR ILL FORMAT UR PC
Guy: no way noob
Noob: U ASK3d FOR IT LOL IM SO LEET I HACKED U
Guy: hey wat doing to my PC u send me fucking trojans didnt you
Noob: Kekekekeke ^^

Get the trojan mug.
1) A popular condom that is often referred to.

2) Most of the people who put a "thumbs down" on this, means that the condom broke on them and/or they didn't put it on correctly that night and they either have a child now(on the way) and/or a nasty STD. which sucks.
1) guy1: Hey I'm about to go have sex
guy2: dude you should totally use trojan! they hardly ever slip unless you don't know how to put it on.

2) guy 1: Dude that condom broke and now my gf's pregnant with twins and i got a STD!
guy2: dude did you slip it all the way down the shaft of your penis?

guy 1: oh crap! no i just put it on half way cause it was a quickie.

guy 2: what a 'tard
