Virus/spyware that blocks google sites?

[dutchmasterflex]

Both of the PC's at my parents house cannot access any google related site..

I can ping google.com but I cannot ping mail.google.com (gmail)

The only way I can access google is through the IP, but still no way I can access GMail..

I've run a bunch of free anitivirus and spyware programs which ahve removed somethings but I still cannot get google to work properly..

Anyone experience this before?
