The Strangest Problem

When i'm trying to watch the messages that posted here' more than a week ago i'm entering some "internet optimizer" site.
Is it just me or some common problem?

You have spyware on your PC. Get SpyBot Search and Destroy to remove the spyware and SpywareBlaster to protect your PC against future spies. Both tools are free, you can download them from the internet.

Thanks, but it didn't help
