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.
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.
This family of Trojans downloads and installs new malware or adware on the computer.
The downloader then either launches the new malware or registers it to enable autorun
according to the local operating system requirements.

The names and locations of malware to be downloaded are either coded into the
Trojan or downloaded from a specified website.
