Your fritzbox, via DHCP, has told your Windows that the search domain is 
fritz.box. However, since recently, there is an actual .box TLD (like 
.com and .net), and inside the .box TLD is a wildcard pointing to 
127.0.53.53. For an explanation of why that is done, see 
https://icann.org/namecollision

The problem is that nslookup appears to be trying the name you type in 
under fritz.box -first- before trying without it. Adding a trailing dot 
to your query (so www.google.com. ) might help, but please be aware that 
nslookup is very buggy.

Kind regards,
