New topic/new website : new thread.
I would need to see screenshots of the (SiteAdvisor/Microsoft) warnings to take this any further.
Having full confidence in your comments regarding www.tulsaworld.com...I have been, since..gingerly navigating-thru (my daily hometown newspaper). This very morning..my viewing was interrupted by a Huge Screen that read "This Site Is Unsafe For Your Computer-complete with large "X" pictured, et.c, etc. giving me an option to click GoBackToYourHomeScreen..which I promptly did.
Being that I didn't dwell long on such an ominous-looking screen..I didn't see WHO initiated it (my Google screen again showed all Green Checks).
MS Windows suggestion, maybe?
