"Is my computer unsafe without an anti-virus running?"
It is as unsafe as leaving the door to your house open when you go to work in the morning.
"Would it mess up my computer if I download another anti-virus program since AVG is screwed up?"
Absolutely not, as long as you uninstall AVG completely. This would prevent any potential conflicts, e.g., with real-time protection, or the new AV reading the other's definitions and interpreting them as actual viruses.
Whereof one cannot speak, thereof one should be silent.
