I recently found kikblaster, snap.do, and several other malware plugins on my computer, and after getting rid of them, firefox will not load any site that isn't HTTPS secured

That's strange. Can Internet Explorer or other browsers access HTTP sites?

For Firefox, could you check whether the connection setting has been customized:

"3-bar" menu button (or Tools menu) > Options > Advanced

Click the Network mini-tab, then the "Settings" button. The default of "Use system proxy settings" should piggyback on your Windows/IE LAN setting, or you could try "No proxy" to see whether that helps.

If that looks normal, or changing it does not help, could you run through these steps. I know it seems long, but it's not that bad.

(1) Open the Windows Control Panel, Uninstall a Program. After the list loads, click the "Installed on" column heading to group the infections, I mean, additions, by date. This can help surface related malware that. Be suspicious of everything you do not recognize/remember, as malware often uses important or innocent sounding names to discourage you from removing it. Take out as much trash as possible here.

(2) Open Firefox's Add-ons page using either:

  • Ctrl+Shift+a
  • "3-bar" menu button (or Tools menu) > Add-ons
  • in the Windows "Run" dialog, type or paste
    firefox.exe "about:addons"

In the left column, click Plugins. Set nonessential and unrecognized plugins to "Never Activate".

In the left column, click Extensions. Then, if in doubt, disable (or Remove, if possible) unrecognized and unwanted extensions. Bear in mind that all extensions are optional, none come with Firefox, and you can learn more about them by checking their reviews on the Add-ons site.

Often a link will appear above at least one disabled extension to restart Firefox. You can complete your work on the tab and click one of the links as the last step.

Any improvement?

(3) You can supplement your earlier security scans with the scanning/cleaning tools listed in our support article: Troubleshoot Firefox issues caused by malware. These on-demand scanners are free and take considerable time to run. If they finish quickly and especially if they require payment, you may have a serious infection. I suggest the specialized forums listed in the article in that case.

Success?
