Folks, thanks for thinking of it. But frankly, having to upgrade C++ seems to me a complexity well beyond what can be suggested to an end-user. I give-up doing this, because I am not sure that a too-recent version of C++ will not make some of my older programs unable to run anymore. To be positive however, I would like to point-out how I apparently got rid anyway of the problem for which I initially wanted to install Malwarebytes. Initial problem: When on the Web and clicking on certain links, I never arrived to the expected site. But instead, on some Google-looking page saying "Not found", or on eMule, to name a few. That happened either with Firefox or with IE6. None of my installed security programs detected any malware, so I wanted to give Malwarebytes a try. While I could not get Malwarebytes to run, following in the meantime the advice on a forum I downloaded and executed Norton's FixLinkopt.exe, that runs in Safe mode. Then I downloaded and executed Fixewareout.exe, that pauses the start of WinXP, and displayed the following report: ________________________________________________________________________________ ________________ Username "utilisateur" - 30/05/2008 12:35:39 [Fixwareout edited 9/01/2007] ~~~~~ Prerun check HKLM\SOFTWARE\~\Winlogon\ "System"="kddnd.exe" HKEY_LOCAL_MACHINE\system\currentcontrolset\services\tcpip\parameters\interfaces\{4E048DA4-DB37-43C2-AF3D-FD7F3FC3267C} "DhcpNameServer"="85.255.114.28,85.255.112.73" <Value cleared.

Once both FixLinkopt and Fixewareout were executed, apparently I got rid of the unwanted redirections. For what you see in this report, should Malwarebyte have noticed and fixed the problem? Hope this helps. I shall check from time to time for the release of Malwarebytes 1.15. Thanks again, Phil
