text: G'day,\n\nFirst... have you changed anything in your internet connection/the way you connect to internet.  Sometimes the problem occur when you have changed the internet/network setting due to different DNS setting.  You may want to chat with your internet provider to make sure that at you do not have problem with your internet connection.\n\nIf they already confirm that there's no problem with the internet connection then II have a feeling that your computer has been infected by virus or spyware.  A few tips as follows:\n1. Run virus and spyware scans from safe mode (restart the computer and press F8 button several times until the option menu appear).\n2. Reinstall IE from the OS CD\n\nIf these basic steps did not fix the problem then you will need to reformat your HDD since the OS has been compromised very badly and this problem is just the tip of the iceberg.  You will need to back-up your datafiles and e-mails (if using Outlook).  Then reformat your HDD and reinstall the OS & programs.  This steps will make sure that there are no bugs and problems with the operating system anymore.  Just make sure you have the OS and drivers CD ready, since formatting will ERASE EVERYTHING in your HDD.\n\nHope this helps.  Good Luck!
