I have downloaded firefox, checked for malware, and checked for virus. Firefox use to work in that environment. Had some malware--corrected and now will not open any trusted site. Keeps saying certificate is not good. I have checked several site certificates and they are good. Help???

Chosen solution

I assume you didn't install Fiddler, which is used by web developers...

The presence of that certificate can indicate malware named Browser Safeguard.

In the Windows Control Panel, Uninstall a Program, I suggest that after the list loads, you click the "Installed on" column heading to group the infections, I mean, additions, by date. See whether you can find BrowserSafe/Browser Safeguard or similar and remove it.

please check your date and time settings and make sure its correct because mostly certificates are not trusted when the date and time is inaccurate
