BleepingComputer.com: Internet works but not browsers

I'm using Windows 7 Home Premium 64-bit.

Lately when I try connecting with any browser it says I can't like the internet is unplugged. But I can download and install Windows 7 updates. I was maybe thinking it was a virus so I installed Malwarebytes and Superantispyware. Malwarebytes wouldn't update but SAS would. It had AVG anti-virus 2011 and I uninstalled it with the Windows built in uninstaller. Then I tried using "avg remover 64 bit" and I got the message "the version of this file is not compatible with the version of windows you are running" which is strange because I have the 64 bit version of Windows. I got suspicious and tried running TDSSKiller.exe, rkill.com and some other AV programs but got the same "the version...". I read in a couple of searches that it's probably a virus and since I can't run any AV stand alone program, I suspect it is. When I ran Malwarebytes and SAS, it showed no virus's which I don't believe. Also everything in the Network and Sharing Center is totally normal showing that all is working fine. So if I can't run any of my anti-trojan, etc. programs, I can't see what it might be. This does the same in Safe Mode.

Which browser are you using?

It sounds like a virus might have changed your connection settings. Most commonly people don't use any sort of proxy. It's possible a virus could have altered your settings. By default Internet Explorer is set to auto detect. Here is a guide to disable the proxy. http://www.ehow.com/how_6347299_disable-proxy-settings.html

All proxy settings are set to off. No change.

SAS has built in repair options for correcting connection issues. If the repair is not successful I suggest going to the Am I Infected section an start a new thread.

If you are using IE you might consider resetting IE back to default settings.
Open IE select Tools; Internet Options; Select Advanced Tab; then click the Reset button in the "Reset Internet Explorer settings"

Sorry for the delay, but I realized this problem has only been here for a week. So I did a system restore (in normal moded) to about 2 weeks ago but the restore got hung up for too long (something about the registry) so I restarted and ran the fix start option. So I guess the restore didn't work and I'm still where I was at the other days.

Here are some notes:

-running Win 7 Home Premium 64-bit
-Only 64 bit IE9 works
-trying to run AV programs like TDSSkiller and rkill.com give a message saying file is not compatible with the version of Win 7 i'm running, unless I need the 64bit versions which I've never needed before
-everything seems normal connection wise (wired and wireless), but Chrome says in options that it is using a proxy to connect, but when I go to change it, it is not set to proxy, just the normal settings
-seems like a sneaky virus, but is it?
-I've run all the anti-virus programs I can, including all the ones mentioned
-malwarebytes won't update but SAS will
