AVG is one the best solutions out there for antivirus.
It's cheap, lightweight, easy to install and doesn't slow your PC. My previous antivirus made my PC move like a snail!. As long as I bought AVG, my PC has restored in its own speed. I can protect home PC, business workstations and my phone with AVG. And, I can control all the devices' security even from my phone!
You don't have to buy different security solutions for your different devices. You can secure them all under one antivirus.
