That might be a (missing) component of Norman antivirus. Assuming you have another antivirus working and no other problems and only help from family and friends and colleagues when you're back in Sweden (so you have no friends or colleagues or repair shops that can help in Amsterdam), I would just accept it as it is for these 2 months.

When getting a laptop from a source that's not fully trusted, it's best to go back to factory conditions and start all over yourself. But that can't be done via teamviewer.
