can I install 2 antivirus programs.

No, absolutely not. The rule to follow is ONE anti-virus program, ONE firewall on a computer.
Using two actually decreases your protection because they end up conflicting with each other and will miss something "coming in the door".
Any ONE of the anti-virus programs you mention are very good. I usually recommend AVG just because of it's ease of use but that is really up to you.
