Every time I start windows, Limewire start also. No Limewire in startup of msconfig. I suppose that the installation has put something in the register to start Limewire automatically. My question is how can I disable this startup ?

This box was already unchecked..
Thats the whole problem...

No

No, once closed it stay closed.

I have followed al these ideas, without results. Delete folder limewire, reconfigure limewire and say no for "start automaticaly".
The only thing I can say is that Limewire now starts later. After windows is started and al startups are done, then Limewire starts a few minutes later. Thahs why I think it must be something in de register files...

Just to be sure, get Norbie to check your system out to see if there is a problem; NorbiesWorld (click on link) Follow his directions carefully.

Great news, I was on NorbiesWorld and after a lot of reading I download the program "ewido anti-malware". After 1 run he found 16 malware things.
A remove of these was the solution. No more startup of LW after windows startup. Thank you very mutch for the big help

Great to hear your problem is solved. Thanks for letting us know.
