I already had a strong feeling that you are Dutch.
Why ?
Your first post here was in Dutch
But this is a English forum (there is also a Dutch one here), so I will continue in English.
I do see some things in the logs that should be fixed.
Amongst them traces of a removed McAfee product and the Olmarik malware.
Just to make sure, you have UPC as provider ?
I will ask Essexboy to have a look at the logs also.
