When I open a folder with an suspected(in fact not) virus inside, this shows up, not the small popup window in the lower right corner of the screen.
Edit:
You can reproduce it in this way:
Set the AV to “automatically quarantine” and disable it
Create a folder named as san&sand or whatever with an “&” inside
put a known or suspected virus into this folder
turn on the av module, refresh the folder, you will see this window
I don’t know, just now I switched from chinese to english and tried again, this HAPPENED again
Maybe it has something to do with de system’s language? It’s a little difficult for me to try then, my system is in chinese
