jmgirman,
This is possibly relevant re your Google redirect.
See here: http://forum.avast.com/index.php?topic=88157.0
If, after reading the FBI .pdf article, you see that you have one of the IP addresses listed in the document, then that is the source of your re-direct behavior. If not I, then someone else here can help reset your modem or router back to default settings, as they or it should be.
Note that the Internet Protocol addresses are in a range from xxx.xxx.xxx.xx1 to xxx.xxx.xxx.225, and any address that fits within that range(s) is probably compromised, as noted by the FBI.
