Why can I no longer connect to legitimate websites?

July 24, 2018 at 12:53:28
Specs: Windows 10, 8 GB
Suddenly, I can no longer connect to legitimate wesites. I am connected to the Internet. However, when I enter a URL into my browser, Google Chrome, I recieve the following message:

Ths site can't provide a secure connection
Try running Windows Network Diagnostics (yeah, like that's gonna tell me anything useful)
ERR_SSL_PROTOCOL ERROR

I tried a different browser (nternet Explorer); same problem.
Is there a glitch in some elusive software file., or...
Is this indicative of a hardware issue?

Any help appreciated.

At the "internet options" > Advanced: scroll to the bottom and make sure the "Use TLS 1.x" entries are all checked. Perhaps a "Reset" op all options can also do the job.

If that doesn't work, what did you install/uninstall/do before the problem started??

Since this happens with two browsers and presumably with multiple web sites, I would assume malware.
Use another working machine and download Malwarebytes, save the installer to a flash drive and transfer it over to the machine. Install the program and run it. Make sure that 'Scan for Rootkits' is checked in the options. Remove all it finds. Copy Paste the results here in a reply for review.
Do the same with ADWCleaner from Malwarebytes.

Thanks, Fingers. I forgot to mention in my original post: I ran both Malwarebytes and AVG Anti-Virus. Neither found any malware. I also ran Adwcleaner, which found and quarantined two suspicious files. But none of that helped to retore my connection to legitimate websites.

Unplug your router and modem (or router/modem combination) for 30 seconds. Plug it in again and while it is booting, restart your computer. This will force your modem to get an updated IP address from your service provider, force your router to reload its firmware from storage, and make your router and computer get rid of any glitches in its running software (in memory). It will also get your computer to get a new internal IP address from the router.

If these do not help, you can run Windows Update manually to see if a bad update is replaced with a newer improved one. After that you can go to the system or motherboard mfg site (factory/custom system) and download all motherboard drivers starting with chipset and including NIC and others and installing the newest versions of each.

Thanks again, Fingers. I tried your suggestions but still not connecting to websites. Now I'm wondering whether my laptop is suffering a hardware issue.

Thanks again, sluc. I navigated there. Use TLS 1.0, 1.1, and 1.2 are all checked. I'm beginning to wonder whether my laptop is suffering a hardware issue.

Any proxy configured? Check on the "connections" tab > LAN settings: Poxy server? or "use automatic configuration script" set and checked?

If connected with a network cable, try a different cable and even a different port on the router or if a switch, bypass the switch and go directly to the router. Also try Wifi if available to test NIC on laptop. If no Wifi on laptop or prior issues prevent its use, you can purchase a USB Wifi Dongle and use that (they are inexpensive).
If connected with Wifi, try a network cable. Try a different network (home, work, friends, etc). If network plug is not available or suspect problems with it you can purchase a USB to Network adapter, they are not expensive and try that (just make sure you disable any internal NIC and install required drivers).

Well, Dear Ladies and Gentlemen, I finally managed to solve the problem, and I feel I have an obligation to disclose the culprit to you.
I may have mentioned in a previous reply I had both MalwareBytes and AVG Anti-Virus on my laptop. In the meantime I borrowed a working laptop, also with MalwareBytes and AVG running on it. While accessing the Internet on the working laptop I suddenly received the dreaded ERR_SSL_PROTOCOL_ERROR. Not only that, but the appearance of the error message was exactly the same as it occurred on my laptop.
The thought suddenly occurred to me that maybe MalwareBytes or AVG was responsible for causing the problem. So I powered up my laptop, uninstalled both, and rebooted. Bottom Line: My laptop can once again access any website I choose to navigate to. I can only assume that the value of some parameter in either MalwareBytes or AVG changed, causing it to not trust any URL.
My next step is to download and reinstall MalwareBytes and AVG, knowing I can uninstall them if the problem occurs again.
Thanks to all of you for your guidance and suggestions.
