From a post in a GRC newsgroup: (sorry, don't remember from who) "DAP (Download Accelerator Plus) DOES CALL HOME at approximately 15 minute intervals! - AND whenever you INITIATE A DOWNLOAD! I installed the little pecker-head earlier today, and just happen to notice accesses in the log of my Firewall program at 15 minute intervals from the 'DAP.EXE' application to address 209.207.233.113 (also during EVERY download I made in addition to the 15 minute intervals). I blocked that address, only to have the little pecker try to use 209.207.233.112 when it couldn't establish a connect at the 1st address. (These seem to be the only two address it attempts communications with)."
General Info: Numerous posts about blocking Download Accelerator's ad-serving function have been made to newsgroups and listserves but do you really want to take chances by having this on your computer?
Methods found online include: Emptying the ADS folder where DA is installed; Adding servers to the hosts file (ads.downloadaccelerator.com &
www.downloadaccelerator.com); Using firewalls to block IPs 209.207.233.112 & 209.207.233.113; and modifying the URL that DL Accelerator "phones home" to in the registry key:
HKEY_LOCAL_MACHINE/Software/SpeedBit/Download Accelerator/ADS/DefaultServer
