Hackers and Hacker Hierarchy

What is a hacker?
A hacker is someone who likes to tinker with electronics or computer systems. Hackers like to explore and learn how computer systems work, finding ways to make them do what they do better, or do things they weren’t intended to do. There are two types of hackers:
White Hat: These are considered the good guys. White hat hackers don’t use their skills for illegal purposes. They usually become Computer Security experts and help protect people from the Black Hats.
Black Hat: These are considered the bad guys. Black hat hackers usually use their skills maliciously for personal gain. They are the people that hack banks, steal credit cards, and deface websites.
These two terms came from the old western movies where the good guys wore white hats and the bad guys wore black hats.


Now if you’re thinking, “Oh boy! Being a black hat sounds awesome!”, Then I have a question for you. Does it sound cool to live in a cell the size of your bathroom and be someone’s butt buddy for many years? That’s what I thought.
Hacker HierarchyScript kiddies: These are the wannabe hackers. They are looked down upon in the hacker community because they are the people that make hackers look bad. Script kiddies usually have no hacking skills and use the tools developed by other hackers without any knowledge of what’s happening behind the scenes.
Intermediate hackers: These people usually know about computers, networks, and have enough programming knowledge to understand relatively what a script might do, but like the script kiddies they use pre-developed well-known exploits (- a piece of code that takes advantage of a bug or vulnerability in a piece of software that allows you to take control of a computer system) to carry out attacks
Elite Hackers: These are the skilled hackers. They are the ones that write the many hacker tools and exploits out there. They can break into systems and hide their tracks or make it look like someone else did it. You should strive to eventually reach this level.
What does it take to become a hacker?Becoming a great hacker isn’t easy and it doesn’t happen quickly. Being creative helps a lot. There is more than one way a problem can be solved, and as a hacker you encounter many problems. The more creative you are the bigger chance you have of hacking a system without being detected. Another huge quality you must have is the will to learn because without it, you will get nowhere. Remember, Knowledge is power. Patience is also a must because many topics can be difficult to grasp and only over time will you master them.

i personally believe that hackers need to learn LINUX clearly, have a great idea of LINUX, and always apply programming on whatever they observe in nature........

AntiVirus Softwares: choosing the best out of many

firstly any computer user must acknowledge that his the antivirus he is going to use must suit his work, like 
home user 
business user
for home users i recommend the usage of AVG or one can use the AVAST free Antivirus or AVIRA , because these antivirus softwares are light and easy to use, and the home internet users never have to worry about the deterioration of the internet speeds, they are not going to effect the inernet downloading speeds
for business users i recommend KASPERSKY or BITDEFENDER or ESET Nod32, because these softwares make thorough checking and suit the business compatible systems, which have greater configurations when compared to home PCs or laptops or notebooks.
Anyway rating of top 10 antivirus sotwares goes as follows:-

1.) BitDefender


2.)Kaspersky


3.)ESET Nod32


4.) AVG


5.) Norton


6.)Avira


7.) McAfee


8.)Avast


9.) Trend Micro


10.) Webroot

tips to overcome crashes of google chrome

Primarly
Try restarting the browser, or else when the chrome browser crashes it on self shows restore the closed tabs.

Whenever possible, Google Chrome will restore webpages from your previous browsing session.
Do you have Internet Download Manager installed?

If you have Internet Download Manager installed, update to IDM version 6.03 Beta or disable the "Advanced browser integration" option by going to Options > General.
Check for conflicting software.

or try installing the latest version of the IDM which is recommended, IDM has become a problem for chrome for many people out there, i experienced it.

You can check for conflicting software on Windows by typing about:conflicts in the address bar. If you have software that is known to cause Google Chrome to crash, it will be highlighted for you on this page, along with any recommended actions to resolve the conflict. In many cases, the conflicting software is malware that needs to be removed using anti-virus software.
Check whether you need a new browser user profile.

check whether your antivirus is blocking some websites and add them to exceptions in your antivius firewall.
some other tips like always try to run:-
1.)ccleaner
2.)Advanced system care
3.)Tuneup utilities
4.)AVG tuneup
personally the ccleaner and AVG tuneup remove a lot of junk from browser and temporary files and whatever browser stores the junk in it.
also always try to keep to the browser light by installing less number if applications from the GOOGLE WebStore.
 

If you see this error message repeatedly, your browser user profile may be corrupted. First try moving the Default subfolder from your User Data folder to see if that fixes the problem:

    Go to Start menu > Run.
    Enter one of the following directories in the text field, depending on your operating system:

    Windows
        Windows XP: %USERPROFILE%\Local Settings\Application Data\Google\Chrome\User Data\
        Windows Vista and Windows 7: %LOCALAPPDATA%\Google\Chrome\User Data\

    Mac OS X: ~/Library/Application Support/Google/Chrome/Default

    Linux: ~/.config/google-chrome/Default
    Click OK.
    In the window that opens, rename the "Default" folder as "Backup."
    Move the "Backup" folder from the "User Data" folder up one level to the "Chrome" folder.

If you continue to see the error, try creating a new user profile to replace your current one.
Check for problems with protected system files.

    Go to Start menu > Run.
    Enter the following: SFC.EXE /SCANNOW (make sure there is a space between SFC.EXE and /SCANNOW). This initiates the Microsoft utility that will scan and repair problems with protected system files on your computer.

Try opening Google Chrome and see whether the error message still appears.


Sometimes SFC/SCANNOW asks to restart the computer to scan it completely
