Please scan with all programs because each program detects different malware.<br>
All these programs have free versions.<br>

<p>Are you running Firefox by any chance in compatibility mode on a more recent Windows (XP) version?
</p><p>Check that you do not run Firefox in compatibility mode or with a reduced screen resolution.<br>
Make sure that you do not run Firefox in compatibility mode.<br>
You can open the Properties of the Firefox desktop shortcut via the right-click context menu and check the "Compatibility" tab.<br>
Make sure that all items are deselected in the "Compatibility" tab of the Properties window.
