Unfortunately, because new viruses are being developed every day there will always be a need for up-to-date antivirus protection. Furthermore, these viruses are becoming increasingly complex and difficult to discover, and as a result the growth in virus attacks is set to continue.
A return on investment is difficult to calculate for antivirus software because, once installed, it will not immediately decrease costs or improve efficiency.
However, it is most certain that at some point your PC or network will be harmed by a virus. This could effectively destroy valuable information and documents, stop your PC or network from working or slow down your system. It can also take a great deal of time to resolve and be extremely expensive in terms of the technical personnel required to fix the issue and the fact that people will not have access to their PCs. The key issue here is what will happen if you don’t have an antivirus system in place.
