Insecure connection errors seemingly at random

WebSpaceships
WebSpaceships

For the past few days some random websites have been giving certificate errors, and I'm not quite sure why. I've been afraid I accidentally downloaded malware or something, but constantly running Malwarebytes, the Windows Defender scanner, and the free bitdefender scan (which, as far as I can tell, doesn't have the SSL issue that the paid version does, though I could be wrong on that and am somehow just missing the option) doesn't seem to pick anything up so I figured I'd ask here. I've reinstalled firefox a few times now, but while it may clear up the problem briefly, it's been coming back pretty consistently. I've been confirming the websites work on chrome, so it does seem to be just firefox. I've attached a certificate from the questionable content webcomic (just to clarify :-p ), which is one of the sites that seems to consistently throw the error, so any help would be appreciated! Thank you!

Hi webspaceships, thank you for the certificate gibberish. When decoded (I use https://certlogik.com/decoder/), it indicates the certificate was issued by Bitdefender, which most likely means your locally-installed security software. Maybe you have a trial of the full version?

Bitdefender sets up as a "man in the middle" of your browsing. In order to read secure connections, it needs to issue fake site certificates. Firefox knows they not genuine.

Assuming the diagnosis is correct, two choices:

(A) Set Bitdefender not to intercept your Firefox browsing

I think you can find the steps here: How to troubleshoot security error codes on secure websites.

(B) Set up Firefox to trust Bitdefender to issue fake site certificates

Try the steps in the following post provided by another user who got them from Bitdefender support:

Check your computer system date and time are correct, otherwise many certificates will be 'out of date' and cause errors!

Hi Fred, thanks for the suggestion! My PC clock had somehow drifted about 10 seconds off, but resetting the PC clock does not seem to have resolved my issue, unfortunately. The date and time now appear to match what other internet-based clocks are telling me, but I'm still getting the errors.

That seems to have worked, jscher. I'm going to hold off on marking this complete for a bit to see if the problem pops up again, but I guess it was bitdefender after all. Not sure what prompted the initial problem, though, since I only swapped to bitdefender after I started having problems and I thought AVG wasn't catching something...

I STILL don't see an option to turn off SSL scanning, but the re-addition of the certificates seems to be doing the trick.

I'll mark this as complete in a bit after I finish this current virus scan and see if the problem pops back up after a restart. Thank you again for the help!
