Guide to Managing Your Computer’s Hosts File

Hosts FileThe hosts file in Symbian, Windows, Android, Mac and Linux operating systems is used to map hostnames to IP addresses. Networked-programs on your system can consult this file to determine an IP address that corresponds to a hostname. IT administrators and home users should protect the file from unauthorized modifications. The use of customized hosts files to block malicious advertisements and links has become a safe computing practice, but malware and rogue programs can still modify the file, if left unprotected.

Find articles and advice in configuring, updating and securing the file in this guide. You can also learn which antivirus, anti-spyware or firewall software has the ability to prevent changes in a hosts file.
