Spyware Categories, Spyware has several categories, namely:

Trojan / Backdoor
Adware
Keylogger
DDoS agents (zombies)
Sniffer cracked password
Browser Helper Object
Kazaa P2P example.
RAT – Remote Access Tool / Trojan.

If we see there is overlap with an anti-virus that is in part a Trojan. The anti-virus solutions are generally able to detect the presence of a Trojan horse in our system. But for other categories such as adware, P2P, hacking tools, generally anti-virus can not enter this category in their detection.

So why tools such as sniffer classified as spyware? There is a reason behind it. As we know that sniffing tools can have two sides, the side of good or useful for administrators. Sniffer can be used by administrators to make a “traceability” or analysis packages on their network. utility network load for capacity bandwidth is also using sniffer technology. Tool IDS – Intrusion Detection System based network also uses sniffer technology to detect an intrusion on a network.

But on the other side becomes a sniffer can be used for purposes that are not good example to sniff user ID and password that is used in a network. Therefore, when the existing authentication system does not encrypt passwords and user identification or a form of “plain text”, then the sniffer can easily see the user ID and password.

In addition, there are categories of spyware that people are happy to install it on P2P – Point to Point Software example is Kazaa – P2P file sharing is very popular. Inside the Kazaa, there are a lot of adware – software ads – because that’s where they get the benefit. This category is included in the “user awareness facility” means a user starts the installation of their own or not via an integrated installation, for example, when doing downloads or access to the Internet
