the main problem here is that copying/moving over the network is stuck and needs manual intervention on target PC!
the way i see it, you have two choices: either don't tranfer malware to the remote computer or else don't use the avast program to protect the remote computer against malware..
if you are wanting to transfer malware to the remote computer, my advice would be not to use the avast program to protect it against malware..
or it is a Win32:evo-gen [susp] warning .... but unless they tell us, it is all guesswork 

... should that be a question??? ...

... yep, it IS a Win32:Evo-gen [Susp] ...

... and it only appears if you copy the file through network to that PC; if you make an on-demand-virus-scan, nothing else is reported: "no thread found"!
Btw: don't know whether I'll arrive to make that screenshot, as there are two files that are affected, and two "virus found" windows are open - and as long I do not close both of them, the windows explorer on that PC is totally blocked. I cannot access the shared folder with a third PC: the message is: that PC is no longer available on the network and you might not have the permission to access that pc as the network path was not found on the network.
I now wanted to open a pic-utility to save the screenshot. I tried that thrugh task manager (open new task), but as soon as I have to serch for the pic-utility, not only the taskmanager-open-dialogue-window is blocked, but even the task-manager itself is blocked - it even does not actualize the memory usage diagram.
So avast is just totally blocking not only the exploerer, but the PC as a whole.
And that's unacceptable!
... and we come to the next flaw: in the "virus found" dialogue, you offer (preselected) to submit the file to your lab for further analysis. I'd like to do that - but then you force me to either "move the file to chest", "block the file", or even "delete it" (immediately). I'm not gonna do that - I'll press "escape" or click to close the window without taking the proposed action (I'd like to submit it, but only if ignoring the false alarm!).
