"Host File Hijacking by Malware

Some malware tries to use the hosts file by altering it so that some 
well-known addresses are directed to the wrong place. Thus, instead of 
going to microsoft.com, you might end up on a cleverly faked phishing 
site. A number of programs will warn you if something tries to alter 
your hosts file. I like WinPatrol. It has many other functions as well.
