Your comp might have a virus. I got a virus called Window 7 once. It prevented me from acceseing the internet. Funny thing though it told me it was a virus lol.
It might be the same malware that hit ironhidegames.com... I removed it but as that site doesn't have as many visits as this one, it will take longer for the warning to go off...
I didn't know that the amount of visits would help in such ways...the difference in visits is expected though since the forums are on this site after all. Good luck fully removing the malware over there as well though!
Please give Yin, Yang, Blaze and Frost a visit, they will enjoy the company!
