Windows Could Not Automatically Detect Network's Proxy Settings

I am running Windows 7 and I use a ZyXEL ZyAIR G-220 Wireless USB adapter for internet. I had a virus called something like Cloud AV 2012 so I used Malware Bytes to remove it and it worked just fine. However, now the internet does not seem to work (there's that yellow triangle with the exclamation point) and when I try to run diagnostics, the message "Windows could not automatically detect this network's proxy settings" comes up. So far, I've tried rebooting, disabling proxies in all of my browsers, and running scans, And I also cannot system restore, because apparently windows security was turned off and there are no restore points
