If someone connects through Windows Remote Desktop from computer A which is secure (with antivirus, anti malware, smart browsing etc.) to computer B which isn't secure thus maybe it's infected and maybe it's not, will that pose any risk to computer A and potentially make it vulnerable in any way?

(For instance computer B's owner is asking for help, but he doesn't protect his computer the way computer A's owner does.)

 

Thank you.

I have never heard of this happening. Unless you send files from their computer to yours there should be no reason to worry.

What about the fact that the clipboards of both computers become connected for example (among other connections that are made)?

Most importantly look what the NSA said...
