This site has a forum with useful advice: http://www.bleepingcomputer.com/forums/forum22.html

Note the recent topics about Google/search engine redirection.

It's probably worth browsing the forum a bit, but if it looks like it's going to take too long, seriously consider rebuilding your machine from scratch. Sure, it might take half a day but you'll have a known good/clean computer at the end.

>># Copyright (c) 1993-2009 Microsoft Corp.

>># This is a sample HOSTS file used by Microsoft TCP/IP for Windows.

>># This file contains the mappings of IP addresses to host names. Each
>># entry should be kept on an individual line. The IP address should
>># be placed in the first column followed by the corresponding host name.
>># The IP address and the host name should be separated by at least one
>># space.
>>#
>># Additionally, comments (such as these) may be inserted on individual
>># lines or following the machine name denoted by a '#' symbol.

>># For example:

>>#      102.54.94.97     rhino.acme.com          # source server
>>#       38.25.63.10     x.acme.com              # x client host

>># localhost name resolution is handled within DNS itself.
>>#	127.0.0.1       localhost
>>#	::1             localhost

>>If you have any un-commented entries following the above, that's likely sign of malware activity.
