INTRODUCTION
What is trojan
Basically trojan is a Program used to gain access the victims computers.
Fully Controls the victims Computer
Used to hack the remote Computer

Update and tighten Windows before installing new security software
To avoid conflicts, do not use two software firewalls or two anti-virus products at the same time. Completely uninstall one before installing another.

Network Threats and Countermeasures
Information gathering
Sniffing

Host Threats and Countermeasures
Viruses, Trojan horses, and worms
Foot printing
