Why do you need anti virus software?

There are other things that can infect your computer that don't hurt the computer immediately. For example, keyloggers. In fact, keyloggers never harm your computer, just the information that you keep stored there. A keylogger is something or someone that can track every single button that you press on your computer keyboard. They are nearly impossible to trace, but anti virus software can keep them out of your computer for good! Without the software, though, you are leaving yourself wide open to them! So, next time someone asks you "why do you need anti virus software?", spread the word. Tell them why it's so important to protect their computer and their information.

 

How to prevent from being infected by virus like Win32/BHO.NJA?

1. Never click on a link or attachment in an email from a untrusted source.
2. Be wary of files with a double extension such as .txt.vb or .jpg.exe.
3. Don¡¯t get access to illegal online contents such as gambling or porn.
4. Don¡¯t download unknown ¡°free¡± software from unfamiliar source.
