Adware are programs that facilitate delivery for advertising content to the user and in some cases gather information from the user's computer, including information related to Internet browser usage or other computer habits
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.
