ComboFix just updated. Delete old copy of ComboFix, download new one, run a new scan, and post log.
It is attached. By the way, I lost internet access!
Please run the following tool and tell me if access comes back... http://www.techspot.com/downloads/5314-tweaking-windows-repair.html
Tutorial's on that page.
No change at all. Office still does not work, no internet connection.
Please open OTL, click Quick Scan and post back log(s).
sorry for not replying earlier, my computer was down with no internet access. I quickly needed Office to work again so I asked some IT guy to have a look. Although I'm not 100 % sure he managed to fix everything, internet and Office work again. I'll let you know if things collapse in the coming days. Many thanks for your help.
