You might want to get your system professionally checked for the presence of a rootkit or virus. We just cleaned up two client systems this week with a particularly sneaky rootkit that only targeted network connections to Google. The only reason the client called us was because their Cradlepoint router was warning them about DNS poisoning and refusing to otherwise load pages for them; there were no other signs of infection. If you opt to check it yourself, you'll want to scan your hard drive, offline, from another system, and use a good tool. Kaspersky's is actually pretty good for this. Or maybe you just have a simple network issue. :-) No way to tell without a traceroute or a ping or some other diagnostics.
