Being redirected

Hi,

Today I started to get a Java upgrade message that redirects me to another site and then wants me to install an unknown application. I checked with the "real" Java site and all my Java plugins are current. When I use my VPN, I don't experience the redirect? Anyone else experience this problem? How can I fix?

Ran Ant-virus and looks like a few bugs were discovered and repaired. All seems OK now!
