Current URL Blocklist  
     

_____________________

NOTE: Malware samples on the Web and on malicious sites have reached levels over 70 million*, with over 55,000 new malicious programs every day. There is no way -any- static blocklist will suffice any longer, so an OpenDNS blocklist should be considered a supplemental list, at best.
It is HIGHLY RECOMMENDED that the Malware Domain Blocklist, which is updated regularly, be put in place as one of the better defense mechanisms in the system.
On the client/end-user side, this can easily be installed by using the Firefox addon AdBlockPlus - with an added subscription to the Malware Domain Blocklist - that can provide dynamic updates blocking known malicious sites. Setup procedure is here** - an added layer of security.

"... malware that connects using an IP address instead of a domain name will -not- be blocked when you use just domain name lists..."

Warning: We strongly suggest that readers NOT visit websites on this list. They all have a history of covert hacks, redirecting the browser to drive-by-malware installations, exploits, spyware, trojans, viruses, and the like, and should be considered dangerous and capable of infecting and causing damage to your system.
