From a router that has a firewall, security suite on the PC to malware. You have a good question and it's a sign that maybe this OS is not for everyone?

When I try to run Windows Update I get the following error message "An add-on for this website failed to run. Check the security settings in Internet Options for potential conflicts. " I checked and all appeared correct. Next I reset to defaults and I still cannot run Windows Update. I ran your Fix it Center program to correct Windows Update the results "Windows Update components must be repaired. Fixed" but Windows Update still will not run.
