text: what is a remote system? i keep getting this message from norton? that a remote system is trying to access my computer? or something like that. is that norton? i always say block. you are doing the right thing by blocking it.  a remote system is another computer on the internet (or network, if you're on one).  a lot of times this can be someone trying to install malicious software onto your machine.  it could be harmless but its not worth taking the risk if you're not sure.
