Ubersource points out the D-Link router/modem firmware forces you to go their website and receive spamvertising about security software. You have to login to the router, go Advanced and OPT OUT to stop this.
This is very poor practice. Opt-out is NEVER ACCEPTABLE, and using a piece of hardware that is fully paid for to perform the spam attack is disgusting.
No more D-Link for me. I trust Cisco has no plans for Linksys to do the same – this is a revolting form of upselling.
