This problem occurred after I removed the Google Redirect Virus, as per the directions and using the apps given here:

The removal of the virus seemed to be a success, as immediately afterword, I checked all three browsers and there were no more redirects. By the way, at this time there was never a browser connectivity issue.
Having gotten rid of the virus, I thought I had better install some new anti-virus software, and I decided on Comodo. Long story short, it only partially installed and now I can neither uninstall it nor reinstall it. For the long story, see:

The problem with the browser connectivity began soon after the Comodo problem, and I'm not sure if the latter is the source of the problem or if it has to do with the removal of the redirect virus.
Either way, I need help getting my browsers working again. I'd truly appreciate it. Thank you.
