Thats ok, it is because there is trojan horse in your computer
Disable the System Restore feature on your computer. If this is still turned on, the system will restore any deleted files, including those infected by the Trojan horse. This can be done by going into the My Computer file and looking for the Performance option. Then select File System, Troubleshooting and Disable System Restore.
Turn on the computer and run it in safe mode. Restart the computer and when the words begin appearing on the screen, press the F8 key. This takes you to a new screen, where you'll select the safe mode option. Let the computer start as it regularly would before you continue.
Go into the Control Panel by clicking on the "Start" button at the bottom left-hand side of the screen and looking for the Control Panel. Select the Add or Remove Programs icon. The computer should then show a list of all programs existing on your system.
Look for programs that include Spyware or adware on your computer and select the Remove program option. Many users have found it helpful to look for programs that they didn't install and those that were installed when they downloaded a game or other program onto their computer.
Open the Windows System folder and delete all files that include the Trojan virus extension. Go through the list twice to make sure you removed all virus files. Then restart the computer in normal mode and check the folder again. If all the files are gone, you'll be ready to move on. If there is any remaining, remove them and restart the computer.
I finally figured out. It was caused by iNetwork Control that comes with the AI suite software for asus z77 sabertooth mobo. Disabled the program and internet is fast again... took me 2 month to locate this problem.... Asus really need to fix their software.....
