How do we avoid from getting infected?

NEVER download anything from people or sites which you were not 100% sure about it.

You must be sure what the file is before opening it, because many trojans will automatically try to spread themselves to friends in an email address book or on an IRC channel.

Beware of hidden file extensions! To reduce the chances of being tricked, unhide those troublesome extensions.

NEVER use features in your programs that automatically get or preview files.

How do we remove Trojans?!?

1. You can restore your computer

2. Try optimizing Internet Explorer Browser

3. Downloading anti-virus software

4. Use the following tools:

The program is called smitfraudfixhttp://siri.geekstogo.com/smitfraudfix.p...-- Just follow the instruction there

then do an Online ewido scanhttp://www.ewido.net/en/onlinescan/...Just remove all those infections

We need to be careful when download something. We also need an anti-virus to protect our computer from be infected by virus.

We need to be a smart user because this can help us from be tricked with nice thing but behind the scenes it infects our computer with a Trojan or Worm.
