Web Browser - Redirecting Problem (!)

Hi

Does anyone know how to solve the "Redirecting Problem" on Internet Explorer(IE) ?
the problem is whenever i type any words in google,when i clicked on the link,it mostly redirecting me to other websites (advertisement websites) instead of the one google indicated and also sometimes there is a pop out window showing the mail registration related with yahoo and hotmail...

It also sometimes happened in firefox but it is lesser than IE...
i believe the system is infected by malware and spyware,so i installed "MalwareBytes - Antimalware" software to scan the system,it has detected some malware and i have deleted it...
but it seems that the problem still persist...

And do "AntiMalware" and "Antivirus" will conflict at each other?because my system have "AVG Antivirus" and "MalwareBytes Antimalware" and when i start up my system,after a few minutes,it will freeze by itself,so i decided to uninstall the "MalwareBytes Antimalware" and somehow the computer stop freezing...

Any help will be appreciated & Thanks

OS - Windows Vista (32 Bit)
