Hello,
As I seen a lot of people are afraid of "Hackers" and so on..... so this topic will be made just to make you more confidence and remember one thing,
No hacker can hack you if you know what your doing.So I will start with the most ways people are getting hacked or scammed... :-
* Phishing Scam : a website that got the same temple of a website you know, and it will ask for your account details or ask you to download something which might contain a key logger or a virus.
- What can you do to check weather its a phishing scam or not?
1- Tools :-
-
http://www.siteadvisor.com/ , its a McAfee tool which it tells you if the website is safe or not... , it check some certificate when registered and so on ..... and if there was something wrong it will tell you ... like this
- Norton Safe Web
http://safeweb.norton.com/ , you just enter the URL and it tells you, its not very accurate because people which really tested the website will be informing the tool so if you got a website and its new it wont know if its good or bad... example try Ambrosia it will say Untested.
2- Your EYES, I use my eyes to check weather the website is safe or not, how? I got Super Man eyes see through it? No...
First check if there is Https, if so then its safe , Example :-
https://www.paypal.com/ , you see there is Security Http Protocol and you will see Certificate name next to it Paypal,Inc. |US| .... and check
https://store.steampowered.com/login/ you will see it too so if ANYONE give you a steam login page which doesn't have HTTPS , then slap him with a fish, he is scamming you.* Key Logging: a file that will send informations to email or ftp of the hacker what ever you type or press.
How to check weather this file is keylogger or not?
1- Anti Viruses, its best choice alot of keyloggers are detected by them and I recommend Kaspersky and Norton, don't use AVG even if the file is saying I am keylogger it will say no, your not.
Note: there is some keyloggers which can't be detected so even if you got Anti Virus do the next step.
2- Just don't open files your not sure about.... or from people you don't trust, personally I never receive any file .exe or .bat from any friend even my dad.
Note: Key-loggers are always .exe or .bat or something executable ... , they can't be Images or music or videos ... but some hackers make the icon of the key-logger as a mp3 player and you just click and ka boom, so check the FULL extension, if it was .mp3.exe then its a keylog file, and even if you opened the file and it was like a game, it can be a game binded with keylogger.

For Steam users :-
1- If someone is asking for any info check his aliases and his screenshots to make sure he is the real one, I know a community got hacked because someone faked head admin and got all passwords from the owner like shaving his ass.
2- Put Steam Gaurd ON, if someone even got the password somehow he can't log in till he get confirmation code from your email so make sure you check your emails if someone trying to get in the steam account so you can change the password and NEVER match the steam account password with the email and use a hidden email that none knows about

.
3- If you bought a game "CD" in real world, then save the key code steam will ask for it if something happens.
4- Just for confirmation, don't type your info in steam login page that got NO HttpS in it.
Sorry if there is some mistakes, this is not final edition

, any mistakes please notify me

Regards,
Killerftw
