Not more than a week ago my computer started malfunctioning. The situation is - My Net is connected, I can download with IDM in full speed, But the browsing speed is almost zero. I can access any site but the speed drops quickly and becomes zero. -Before the net get's connected, the connection icon in XP taskbar shows a prolonged searching for network and finally gets connected. It is unusual. - I have a WIMAX connection, It cannot connect to network in my PC but it works fine in other computers. - First i thought it's a problem of my internet provider but they ensured that other computers in the line are running fine. By this time i started using my brother's computer and transferred all my files to my brothrer's PC and gave my HDD a full format using 'killdisc'. Then i reinstalled windows and i was surprised see that the problem still exists (I haven't changed the windows it a bit. it is a fresh installation) and by this time my brother's PC got infected and started showing the same problem, i am now stuck with two PCs that can download with full speed but can't browse. I am using XP, MY brother's PC is 7. I have performed the preliminary malware removal procedures and i am pasting the results here. Please help me.
