Keyboard has poor pressure point, seal damage and the pre-installed viruses Scaner has two Trojans found

I must say I would have expected more for the money, although the laptop makes a quality impression, but considers this at the Tastur not, it feels the pressure point as if it were a toy keyboard (special at the Space with your right thumb) , thus it kommte faulty attacks. The screen makes a good picture and the SSD work at the present time soon.
For me the seal of the laptop was damaged, as no activation and data were stored, but I have to keep the laptop anyway (no objection). I had to discover two Trojans in the first scan with the pre-installed antivirus software (McAfee), as these have come to this, remains unknown to me, but to send a entsiegeltes device as I would have expected more from Amazon (although there was a flash offer ) and hope that this will remain a unique case.
