Lets be a little bit more serious
a.k.a. gamerboy:
Buy a condom then when you plug your internet in, put a condom over the plug and jam it in (making sure the condom don’t get a hole in it). Then the backdoor cannot be used and you are 100% safe.

@ most above posts: ��
Use a firewall. I’ve heard the Ashampoo firewall is good, but i saw some hacker pics showing their victims using it, and they still connected.
I used Comodo firewall once, awesome blocked several attacks.
Today i use Avira Premium Security Suite, awesome firewall and antivirus. I wont change for nothing, since all antivirus test sites gives the max or almost the max rating for it, if u need a key for it, PM me.
