I have installed symantec endpoint protection on windows server 2003, and i deployed antivirus on almost 25 computers connected to domain. I feel the pc's in the network become slow after installing symantec endpoint protection and i also notice that its scanning randomly anytime and updating virus definitions during working hours which is causing the speed of the computers very slow. I applied some policies on symantec endpoint protection to scan pcs at mid night 11pm and update virus definitions at 1 am. But still when i arrive in office in the morning users are complaining that their pc's are slow. Please help me in solving this problem i want to make my network and computers faster.
