need help getting "unhacked"

Well, my brother likes to fuck around and fuck with me so, i know he hacked my computer some how and im pretty sure he brute forced it. I don't know much about it or hacking in general but he can connect and disconnect using command prompt. Please tell me ways i can find out more or make it so he cant't access my computer. thanks :/

 

If he brute forced it, can't you just change your password? Or change your IP, because that may be the way that he's connecting to your computer. Try and check his computer when he's not around and see what software he's got going.

What exactly is he doing to your computer?

 

Run a full system scan with spybot maybe ?
Also you can install zone alarm - that won't let anyone connect

 

your bro hacked just to fuck with you? your bro is a dick
the only thing i would do is (if older) punch him in the crotch and tell him to stop and (if yonger) find a hook hanging somewhere in your house, grab your brother, hang him by his beltloop underwear etc. get a paintball gun (or a wepon on your choice) and enjoy ^_^

sorry but no serious answer here but i felt that i should give that example

 

Get a firewall...

 

lol that should sum it up

 

wich do you suggest?
