How to Delete Unwanted Websites that Run Automatically

By Michael Monet

While surfing the Internet, you may stumble upon a site you did not mean to visit and invite a host of unwanted activity to your computer. Spyware and parasites can infect your computer without your permission, running as they pleasing on your operating system. One possible result of this is an unwanted website that continually pops up without warning. Restoring your system and installing necessary software can eliminate this problem.

Select a free antivirus program or purchase one. You can begin with the two free programs available on the Microsoft website, "Windows Security Essentials" and the "Malicious Software Removal Tool."

Step 2

Open a new browser. Search "Microsoft Help." Select "Windows Security Essentials" or "Malicious Software Removal Tool." Click "Download" to download the program to your computer. Download and run only one program at a time.
