I’m not saying Symantec antivirus is not good but it is really heavy for a personal computer used at home or office especially those PC running on below 2.4Ghz and 1GB RAM. Too heavy it slowed down the loading and multitasking when you’re working or opening browsers.
I prefer to go lightweight with antivirus which doesn’t eat up your RAM or CPU processes, thus you will have a faster loading in programs. Here i’ve compiled a list of best antivirus software & free antivirus which is lightweight which doesn’t use up much of your memory resource consumption.
