I may have fixed the issue

I went into AVG's firewall section and chose to restore defaults. Chrome seems to be loading faster, and hopefully will continue to load. I'll let you know if that was the fix. Another issue, which wasn't a factor with mine, is that sometimes the LAN settings ask for a proxy server rather than automatically detect, and unchecking the proxy and checking the automatic detection can help. But like I said, that wasn't my issue. I'm thinking it was the firewall. We'll see.
