Internet stops working after downloading for approx. 30 mins. Hi, really hope someone can help me out on this because its driving me insane.
I'm using Windows Vista 32-bit. Basically, the problem I'm having is my internet browsers stop loading pages after I have been downloading for a certain time (or maybe a certain amount of data?), This includes Internet Explorer as well as Firefox. The funny thing is that I can still sign in to MSN messenger and I found I can still ping websites (after searching google, found that ability to ping was a standard request of Mods in other forums) and my Network status shows no problems even when i "diagnose and repair". This problem has been bugging me for a while now, I even formatted my c: drive and re-installed windows but the problem is still there! Surely it cannot be a virus/spyware etc? I run daily scans with Malwarebytes, Superantispyware and have had Bitdefender installed since starting the computer for the very first time!

I have a friend who used the same Vista cd I used to install, and he seems to be having the same problem. As he is in a different house, the internet settings surely cannot be a factor? The common factor seems to be the installation CD, is that even possible?

Have you tried disabling BitDefender?

Sorry, moved this post to the browsing forum and had marked it solved there. Disabling (or uninstalling more accurately) bitdefender did the trick. Thanks Anyway.
