Error 137 (net::ERR_NAME_RESOLUTION_FAILED): Unknown error

Question

That's what I'm getting. I have an Internet connection. Most sites load, some don't. There is no scheme like, a specific site doesn't load or it happens at a certain time. A random site at a random time will have this problem and I have to reload the page 100 times before I can visit it. The same happens in Firefox.

So far I restarted my router, put the Ethernet cable into another router slot, restarted the PC and reinstalled my browsers. The problem is still there and happening. I have no viruses, at least Malwareantibytes and antivirus software tells me that.

I don't really want to reinstall Windows 8. Anyone have an idea what is causing this?

Answer 1

If you are using FireFox as your primary Internet Proxy, do these steps: 1. Reset your security protocol to "nil" (you can change it back later) 2, clear all cache and set same for max 1024 mg, [no less or more, important!] 3. Reboot PC in safe mode 4. clear IE's cache 5. Reboot, then 6. Restart FireFox

Your problem should clear. Demonstrable error and per-configured error in cache designed like normal .exe program but actually virus recognised by Norton Anti-Virus programs as being Trojan.
