Major (Weird) Internet Problem After SMC Reset

[illinirazorback]

I've been having some speed and battery charging issues on my late 2012 MacBook Pro (15" i7, running 10.9.5). So based on some articles and forum posts, I decided to reset the System Management Controller (SMC) using the Shift-Control-Option-Power Button while the computer was shut down. Upon restart, everything seemed fine, except most websites will not load now. Weird thing is that a lot of other internet traffic is still fine. "Normal" sites (news sites, Amazon, weather sites, Apple, MacRumors, etc) will not load. Browser says it is waiting for a response and it times out. However other sites and web traffic that seem more "secure" (Facebook, Twitter, Dropbox, all email, CrashPlan, iCloud) all work just fine.

Things that haven't worked:
Restart (duh)
Modem/router reset
Different networks (wired or wireless)
Different browsers
PRAM reset
Time Machine restore from previous day when it was working

Things that do work (but aren't fixes):
Everything through the Tor browser
Restarting in Safe Boot

The latter obviously seems like it would be something new I installed, but I didn't do anything except that SMC reset.

Help?

So I'd thought I'd update and bump in a seemingly futile attempt to get this figured out. I did a complete wipe and reinstalled everything from scratch. Worked great, for a while. Now it's back doing the same thing, even after I installed Yosemite.

I can't find anything like this on any support sites or blogs. It's really infuriating!

Thanks in advance.
