If you buy a farmbot, they just do it for you trought teamviewer and it does not really lagg,
Yes farmbots are undetectable but make sure if you buy a farmbot you can enable Virtualization in the BIOS when booting your pc up..
If you have an acer PC/Laptop you most likely don't have this feature and thus can't run farmbot.
All you have to do to startup is open VMware, run the setup and then login and that's all.
