Generic Security Alert for mismatched web certificate at boot up

[treeski]

Hey all,
From just this morning I started getting this annoying window each time I boot up my computer. I can't remember having done anything that would have caused this. Anyone know how I can stop it or figure out why it's happening?
Thanks!

Investigate your network places. Investigate events logs. Investigate startup programs. HiJackThis (HJT) is an excellent tool for this.

There are plenty of fake alerts. I would have expected your description to have implicated a browser. If your AV and/or FW protection is current, there is a small risk to inspecting the certificate to further analyze the source.
