AVG AntiVirus Business Edition can work/update well on server and each computer separately. However, when I initially intended to install it on server and centrally control all computers for my business, it is too difficult for me to handle, so I turned to an IT man for help. What’s worse, after the program is set up, I found everything is largely slowed down with the central control function, so I had to give up central control and manage it separately. Now everything goes well.
