How to protect my computer from hackers?
I have been receiving threats from a hacker. Saying he knows my ip, address, zip code, etc. He also says he is going to hack into my computer "mainframe". What is that? What can I do to protect myself? Honestly, I'm scared. It's no random threat either, it's from a person who hates me because I want nothing to do with them anymore.
Please, anything you know would be extremely appreciated.

security is in layers
1 hardware based firewall aka stateful
make sure and filter unknown mac's
turn your wireless off
use ethernet cables
2. software firewall
sudo apt-get install firestarter
configure firestater - there are guides online
sudo apt-get install clamtk
-its free and open source cross platform
encrypt your home direclty - when installing set as "true"
download truecrypt and encrypt your entire drive
*make "cryptainers" to drop your files into
sudo ufw enble
install "noscript" into firefox
install ghostery into firefox
7. install openvpn onto the computer and configure
8. Intrusion Detection
its called "aide" or advanced intrusion detection environment - library
9. harden your kernal
look in the ubuntu software center and search "harden" this software package will allow you to configure your computer kernal and harden vs unknown attackers.
10. hardened os install
read all of it its so useful
11. use your computer just as hardware -
If my computer were to catch fire would i lose anything but hardware? no..
the data is more imporant then the hardware so always back up your data to an external drives and make 2 copys of each file. you can use a service to auto backup files for you called "ubuntu one" for free.
this hardens your computer in many many ways
take a read and
sudo apt-get install selinux
or get the library from the ubuntu software center
13. system audets
go threw and scan your system with rootkit detction software and look for unknown running services
check system logs
14. known programs that cause system insecurity
check system with grc.com and scan ports
turn off remote acess
turn off remote ssh
15. I know your a windows user and do not disregard what i have wrote. Take into consideration that windows has MASSIVE SECURITY ISSUES!!!
16. sudo apt-get update
configure your "update manager" to check your security packages hourly and make sure to install and reboot if necessary. Since my systems are rebootless its not necessary.
Only boot into your windows partition or computer for services that cannot run on ubuntu or linux distos
ubuntu is way more secure then windows any day
web/office/games/picture editing/media/secure tasks
video editing / photoshop / steam client
people program virues have gotten so advaned there's a term for the new virues called "fud" or fully undetectable
never run wine under sudo as even on linux they can be cross platform and wine will never sandbox those programs.
When your in windows disable programs that are not nessary as some programs have explotes people can explote to access your system.
always keep your system up todate with security packages - windows and ubuntu
If your windows partition does become remote accessed you can use your linux system on the same computer to wipe the virus and do a secure boot.
best of luck!

it does not matter if someone has your ip address since you show it when ever you connect to a website. At most they know who your isp is. so dont worry about it.
if you feel your in physical danger contact the police or the fbi should be your first step then when your mind is clear and stress free work on your computer. feel free to pm me @ my youtube account if you encounter any problems hardening your system.Source(s): I am trained and work for academi http://ubuntuforums.org/showthread.php?t=510812/

Clean your computer of cookies, spyware, trojans, malware, and any other infection. Then change all the passwords to any account set ups that you have online.
Make sure that your computers firewall is top of the line. Not some generic junk. When it comes to your computers protection you always want the best especialy when tax season comes around.
Don't want a hacker getting your social security do you?
