After installing Win 7 Service Pack 1 and IE 11 the hard disk light is continuously ON and Win 7 slows down considerably, in the resource monitor MsMpEng.exe, svchost.exe (...) show very high number of hard faults, then I manually stop all these processes and 5-10 minutes after doing that the OS is back to normal, what is the cause and remedy for this?
Update: This happens only when I go online with chrome or opera and open multiple tabs, if I am not surfing the web then everything is fine. The svchost.exe(netsvcs) is the biggest memory hogger.
