Lansweeper claims All workstations are without Anti-virus software.
GFI Acqquired Vipre.
In some version ( I do not know which) they renamed the agent from "VIPRE" something to "GFI Business Agent"
The service continues to be named " Vipre Business Premium "
I solved this for Vipre version 6.2.5 by Adding %GFI Business Agent% to the list of Anti-Virus Software name.
