I have had some major issues with several websites- where the sites will not fully load. I have searched and SEARCHED the internet looking for advice and I'm constantly told it is my virus scanner that is likely causing this. I have tried everything with it- but not even knowing FOR SURE that is what is causing it- I'm not sure what to do.
I've added a pic of what the sites will pull up like- this particular one was myspace. But there are a few others as well like facebook.
When this first started, I had purchased my computer and all was perfect for several months. Then one day a couple graphics on MS wouldn't pull up. Then within a week or so- a couple more went... then a couple more- until there were NO graphics on my account OR anyone else's either. I CAN see pictures if I have put them on MS using another host site like photobucket etc. I can also see all my friends' background themes on their myspace accounts and as well as some slideshows- which I assume are hosted on another site and linked in MS?
Now OTHER people can see my pics no problem- and I can also see ALL (mine included) on my old computer running XP... but not on this one (running vista).
I have posted this on Vista forums, MySpace forums and you name it! First everyone says ro clean the cache/temp and all that- BTDT. It's NOT that

Then they all seem to think it's got something to do with my virus scan or firewall. But I have shut OFF my windows firewall and still nothing is changed.
So I'm posting here to see if maybe you have an idea if it could be an Avast! issue- and if so- maybe you can help me to fix it
