AVG does not change your HOSTS file but it will alert you that the HOSTS file has changed since the last scan. If you did not make any changes, then you need to investigate what the changes are. What security programs are you using? Some programs like SpySweeper have features that can add entries to your HOSTS file and that action may be detected as a change.

The HOSTS file should not show as changed unless the user is aware of a program needing a change made to it and is aware that it is being altered. Protection softwares and also Malware's will often change this file so they can affect where a computer goes to on the internet.

This is one reason why the user on this system needs to look at the file to make certain that something didn't change it and if so determine if it is a good or bad change...

General system maintenance can change the file even when it isn't apparent by visual inspection. AVG uses a checksum to compare a file before and after and a minor change or correction to the file could have caused it to appear changed.

Host file changed
Re: C:\WINDOWS\system32\drivers\etc\hosts

The HOSTS file is a text file that has no extension and can be viewed using notepad. At the top is an explanation of the simple syntax. Each line is an IP address, a domain name, and an optional comment placed after a # sign. A HOSTS file maps an IP address to a name.

The HOSTS file is found in these default locations:
Windows Vista -> C:\WINDOWS\SYSTEM32\DRIVERS\ETC
Windows XP -> C:\Windows\system32\drivers\etc\hosts
Windows 2K -> C:\WInnt\system32\drivers\etc\hosts
Windows 98 -> C:\Windows\hosts
Windoes ME -> C:\Windows\hosts

An example HOSTS file is shown here.
