BleepingComputer.com: some websites load REALLY slow!!

I am not sure what the problem is exactly, but certain websites, (ex. myspace and kongregate) load extremely slow. It seems that if there is a shockwave app, or anything of that nature, the website takes forever to respond, this website in specific, loads at a normal speed, which is very fast. i've tried un-installing and re-installing shockwave, used kapersky, anti-malware, and virtumondo-begone and even with all that cleanup they did, the problem still exists. help here would be greatly appericated!!! thank you for any help that comes my way!!
