None of the words you have typed in any of your threads contain links to anywhere. You probably have a virus or Malware. I would recommend a complete system scan. If you are using a good Internet Security software product, run a FULL system scan. if that fails, Format your hard drive and start all over. Make sure you back up all you stuff. Another option would be to buy a new hard drive, mount your software (O.S.) then your anti-virus and then slave your original hard drive to remove any viruses of Malware problems, and use it for storage. If you use a Laptop, you can still mount your infected hard drive through a USB port, and then scan it.
