Yesterday my Firefox seemed to spasm and I believe I had a virus (every time I hit the "home" button which is google.com for me, it would send me to this weird site that I knew wasn't safe). I uninstalled and re-installed Firefox and ran virus scanners but nothing was found. After restarting Firefox, every website that I try to go to is giving me an unsafe error and that I must give each site a security exception, even for safe sites like Facebook, Twitter, etc. Once I did get on Facebook, everything is in HTML format and I can't use it at all I tried restarting/uninstalling/resetting Firefox again but to no avail. I checked my Firewalls and nothing came up. Here is the data from the troubleshooting information.

Hopefully you can figure something out as I love Firefox but it's very frustrating that I can't use it and that this is happening. I also use Avast! Anti-security but I'm fairly certain that is having no effect on this problem. As I said I've also ran malware and virus scanners but nothing came up harmful.

Hello,

Try disabling Avast's web shield and try going to a few safe sites where you experienced the "untrusted connection". You can also follow this article for other common troubleshooting steps: "This Connection is Untrusted" error message appears - What to do.

You can try these free programs to scan for malware, which work with your existing antivirus software:

If your home page is has been changed, and you don't have any suspicious extensions:

  • Tools (or New Fx Menu ) > Add-ons > Extensions

You can use the Search Reset Tool to reset your home page, new tab page, and search bar back to default. The extension then uninstalls itself once these preferences are reset.

Let us know if that helps.

None of those actually worked but I did have AdGuard which i believe was the culprit to nothing working. I uninstalled it and everything seems fine now. I think I'll just stick with adblock. Thanks anyways.
