Using this filter subscription will also require 20 MB more memory and up to 25 MB download bandwidth per month. Congratulations to everybody who helped optimizing JavaScript, the results are really incredible! The big surprise was Firefox 3, there the delay is only 3-4 seconds. In Firefox 2 this took around 20 seconds which is why I recommend against using this subscription there. The bad news: loading/saving the list still takes a while (noticeable as browser startup/shutdown delay). It is the first time I tried Adblock Plus with so many filters, and the good news is: the slowdown during browsing is in the area of single-digit millisecond numbers, that’s not noticeable. So now Adblock Plus users can add a subscription with slightly over 40000 filters that will block access to the known malicious domains. The list is mainly meant for DNS servers, but why not try to use it in Adblock Plus? The script to convert the list was easily written, discussing the matter with the author of the list and finding hosting for the Adblock Plus filter subscription took somewhat longer - but now it is all done. I searched for other lists of malicious domains and quickly found one aggregating multiple sources of information including Dancho Danchev’s blog posts I linked to above. Not sure what Google’s scans look at, but I guess they simply have a different focus - the idea is to block sites the user might go to unintentionally rather than malicious Flash objects that could be easily served with ads for example. It might have been that the sites were too new, yet the information on Google for some of the older domains indicated that these have been scanned and nothing objectionable could be found. Of course I checked the malware filter in Firefox 3 first, yet it didn’t recognize the sites as malicious. Yet the domains participating in the attacks are known, so there must be a way to block them. So Firefox users were at risk here as well, and the continuing waves of SQL Injection attacks inserting malicious iframes into trusted websites didn’t exactly make the situation better. It turned out that the Flash vulnerability used was already fixed but that doesn’t really matter - Adobe seems incapable of updating users to a secure Flash version in a timely fashion. I was reading about yet another wave of attacks exploiting a Flash vulnerability. If you want to comment on the lifehacker article - please do so on. If you need some info on Malware Domains list or want to comment on it - is where you should go. While it is great that lifehacker decided to mention my two years old blog post, I don’t really feel like reading comments from people who didn’t bother to read my blog post.

You must be signed in as an administrator to edit the Hosts file. Windows 10: HOSTS file blocking telemetry is now flagged as a risk | bleepingcomputer This tutorial will show you how to block websites for all users on the computer using the Hosts file in Windows 7, Windows 8, and Windows 10. Using the Hosts file to block websites by domain is preferable to trying to use rules in Windows Defender Firewall to block IP addresses since websites will often use more than one IP address. Entirely blank lines in the file are ignored. Comment lines may be included, and they are indicated by a hash character (#) in the first position of such lines. Each field is separated by white space (Tabs are often preferred for historical reasons, but spaces are also used). The Hosts file contains lines of text consisting of an IP address in the first text field followed by one or more host names. The hosts file is one of several system resources that address network nodes in a computer network and is a common part of an operating system's IP implementation. The Hosts file is used by the operating system to map human-friendly hostnames to numerical Internet Protocol (IP) addresses which identify and locate a host in an IP network.
