Depending on the web browser you use, its version, settings, extensions and plugins installed, it is sometimes enough to visit a website to become a victim of a successful malware attack. There are a couple of things that you can do to protect your system and yourself, including making sure that everything is always up to date and that you have at least one security suite installed on your system that may catch the attack before it is executed successfully.
Mirage Anti-Bot is a free program for the Windows operating system that will add a blacklist of websites, domains and IP addresses to the Windows hosts file to block connection attempts to these sites automatically when they occur.
The program uses information provided by abuse.ch which maintains a database of known malware related websites. It should be clear that the protection is not 100% as the list does not contain all known or future malware domains and sites yet. It does however take care of popular sites used to spread malware.
If you are using a service to automatically blacklist sites using the hosts file, you may want to check if abuse.ch is already included. If that is the cause, there is not really a need to run Anti-Bot in addition to the other program. If you do not use any program yet, Anti-Bot may be a good start.
To add information to the hosts file install Anti-Bot on your system, run it with administrative privileges - and not after installation using the check box - and click on the update button to download the latest site list and update the hosts file with it.
You can check if the hosts file has been edited by opening C:\Windows\System32\drivers\etc\hosts in a plain text editor such as Notepad. All domains are redirected to 127.0.0.1.
You can exit the program afterwards as it is only needed to update the hosts file. You may want to run it regularly though to work with the latest data set.
I recommend you enable the logging of connection attempts to sites that are automatically blocked in the program settings.
If your resident anti-malware solution does not block bot-related websites then you may want to use the program to add protection to it using your system's hosts file and the abuse.ch block list. While it won't keep everything out, it includes many popular attack domains.
