Adware are programs that facilitate delivery for advertising content
to the user and in some cases gather information from the user's computer.

BHO (Browser Helper Object) Trojan.
The BHO waits for the user to post personal information to a monitored website.
As this information is entered by the user, it is captured by the BHO and sent back to the attacker.
The method of network transport used by the attacker makes this Trojan unique.
Typically, keyloggers of this type will send the stolen information back to the attacker via email
or HTTP POST, which can appear suspicious.
Instead, this Trojan encodes the data with a simple XOR algorithm before placing it into
the data section of an ICMP ping packet." explained the company.
Backdoors are the most dangerous type of Trojans and the most popular.
Backdoors open infected machines to external control via Internet.
They function in the same way as legal remote administration programs used by system administrators.
This makes them difficult to detect.

Backdoors are installed and launched without the consent of the user of computer.
Often the backdoor will not be visible in the log of active programs.

Once a backdoor has been successfully launched, the computer is wide open.
Backdoor functions can include:


  • Launching/ deleting files

  • Sending/ receiving files

  • Deleting data

  • Displaying notification

  • Rebooting the machine

  • Executing files




Backdoors are used by virus writers to detect and download confidential information,
execute malicious code, destroy data, include the machine in bot networks and so forth.
Backdoors combine the functionality of most other types of in one package.

Backdoors have one especially dangerous sub-class: variants that can propagate like worms.
A Search hijacker redirects search results to other pages and may
transmit search and browsing data to unknown servers. An error page hijacker directs
the browser to another page, usually an advertising page, instead of the usual error
page when the requested URL is not found.
