Trust BHO

Removing Trust
Categories: BHO,Hijacker,Toolbar
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 desktop hijacker replaces the desktop wallpaper with advertising
for products and services on the desktop.
Toolbar presents itself as a helpful add-on for Internet Explorer but it is a real pest.
It replaces your start page, continuosly open a number of pop up windows and so on.
