Cydoor

Cydoor comes with Kazaa, imesh etc. If you use Kazaa lite they have dummy Cydoor files meant to spoof Cydoor and make Kazaa work. Cydoor is there for its Ads OnSoftware™ ability. It is what serves ads on Kazaa, for example, keeping Kazaa free.

Cydoor is adware that sends info to the following domains:

rgs1.net
rgs2.net
cms1.net
cms2.net
bns1.net
bns2.net

It's not a trojan it's is not a danger but it does download executable code and it does transmit surfing information to serve ads.

Cydoor downloads ads while you are online for offline ad displays.

Cydoor used to embed itself in the registry, it is better now than it used to be but it is still adware.
