Any antivirus program that is to be an effective tool in fighting malware, has to hook in to run at startup and need services to be running in order to properly protect you PC. Any program that does not do this, will not be that effective and any virus, trojan....etc could easily bypass or shutdown that kind of antivirus program. Any antivirus program that only runs when you tell it to run is basically just an on demand scanner and does not protect your PC.
If you shut down your antivirus program and your PC is still connected to the internet, you are putting your security at risk just to play games.
There are antivirus programs that are not as resources hungry that you should try out. Also never use any internet security suite (the everything package) as they are all resource hogs.
Check out the below but only install one antivirus application at any given time. If you want to install another, make sure you completely uninstall any other AV first.
