Windows XP How do I enable inline frames in my browsers?

[Cache-man]

I recently installed and applyed all manor of security software on my PC due to a recent virus problem, and now my Browsers (Firefox primary, IE secondary) will not support inline frames.

I noticed this while checking the weather updates on one of my sites http://www.secretofthemed.com/live-weather which I used to be able to access from my main PC, but now I cant (although it still works on my laptop). I am presuming that one of the security packages i installed must have disabled the inline frames.

Does anyone know if there is a option somewhere in Windows, or maybe the browsers to turn support for inline frames back on?
