Sure. Use AVG Remover: AVG Antivirus and Security Software - Tools download

Your better options:

- Avira free antivirus: Avira AntiVir Personal - FREE Antivirus
- Avast! free antivirus: http://www.avast.com/eng/download-avast-home.html

- free Comodo Internet Security (firewall + AV): Firewall AntiVirus Software Free Download from Comodo
NOTE. During installation, Comodo will also allow you to install AV only, or firewall only, if you prefer to combine one Comodo product with some other product.

If you decide to install Avast, or Avira, make sure, Windows firewall is turned on, or use Comodo firewall..
If you decide to install Comodo Internet Security, or just Comodo firewall, make sure, Windows firewall is turned off.

IMPORTANT! Make sure, you use only ONE antivirus, and ONE firewall.
