Another problem comes..

After reformat for sure all the virus is gone right?but right after i format my laptop..i visited a website on my search..then the nightmare begins..
I not that sure when is that but im sure the virus is named

'TrojanDownloader:Win32/Lenos.Lx'

This virus cause me a lot of trouble as it continuously search for advertisement at the websites..i remember that time is during the night time..During the time i almost fell asleep..i went to toilet and brush my teeth..
I suddenly heard my laptop got speaking itself..Damn i thought is what thing during such late night..scare me..
As my speaker on quite loud too..luckily it not sent me an scary advertisement during i surf web at night time...as you know the suddenly pop-up ghost on your screen after you concentrate on your laptop screen is quite effective
Moreover it helps me to stop my security services and antivirus..means that it does not have any protection at your laptop..

Then i use this tools to solve my problem..which named Combofix..just download from the website and double click it..it will help you to readjust back your setting and remove the harmful viruses..Quite useful huh..
