Hi everyone! Currently we have installed Clamav and Sophos Antivirus. I'm considering to install Comodo Antivirus, but I don't know if this will be beneficial or won't have any impact in the battle against virus. I'm not worried about the performance, the server has plenty resources and low traffic. Thanks in advance for any advice. Good day!! Hugo Manuel Ojendz Lemus | HAL México
