internet explorer

[roger]

When I start internet explorer a different web address
appears in the address bar and I'm unable to change it
through "Internet tools" Do I have a virus?

Some website has hijacked your homepage.

1. Use the following scanners to find and remove the website.

SpyBot S&D searches your harddisk for so-called spy- or adbots;
http://security.kolla.de/
or
Adaware
http://www.lavasoftusa.com/software/adaware/
or
CWShredder
http://www.spychecker.com/program/cwshredder.html

2. Some porn websites redirects links to their websites using your HOSTS
file. Do a search for the HOSTS (without extension) file and remove the
entry.

3. If still no joy, download HijackThis from Spywareinfo download page

http://www.spywareinfo.com/downloads.php

Run the program and you will find many entries. Most are OK. Post the log. I
will find the problem for you.

4. For future preventive maintenance, make sure programs cannot just
download on your computer without your permission. From the Internet
Toolbar, go to Tools > Internet Options > Advanced. Make sure "Enable
Install On Demand (Internet Explorer)" and "Enable Install On Demand
(Other)" are unchecked.
