Some Sites Suddenly Won't Load On My Pc

This week, I suddenly had several sites that would not load on my PC, including MajorGeeks. I normally use Palemoon, but tried the same sites using Firefox, Chrome, Opera and Internet Explorer. The sites do load using my wife's PC. Any suggestions?
Thanks
Joe

 

She does not use Palemoon. The sites do not load on my computer on any of my installed browsers. I did disable all plugins, reloaded Palemoon, but they sitll would not load. I uninstalled Palemoon, reloaded, rebooted and the same sites still do not load.

 

Try Flushing your DNS resolver Cache.

Open a Command Prompt with Admin Privileges and type;
ipconfig /flushdns
(Note: space after ipconfig)

Reboot, then Retest.

 

Ran ipconfig /flushdns, reboot, still can't load some pages.
Windows 7 Home Premium, Service Pack 1. 64 bit

 

Launch a command prompt and see if you can ping those web sites. Not all sites will respond to pings, but some of them should (it would help if you could provide a list of the unreachable sites).

If you can't ping any of the sites, install Malwarebytes and scan your computer.

 

Pinged sited on my computer and my wife's. On my computer, they timed out. On wife's they pinged. Sites pinged weberbooks.com, userfriendly.org and thedailygouge.com

 

If a DNS flush did not suffice, then its highly probable that an unwanted, embedded script is redirecting your requests.

Can you please run Hitman Pro
(please select 'One-Time only' scan so as not to register).
Remove all found, Reboot and Retest.

 

I was away from my co.puter for several days.Ran Hitman Pro, found nothing. Rebooted no change

 

Hitman found nothing at all??

 

Yes, Hitman Pro reported no threats found.
The only thing in hosts is 127.0.0.1 localhost
DNS servers are the same.

 

OK, I am trying the malware removal guide.

 

Well it looks like TimW has given you a clean 'Bill of Health' over in the Malware section, so my next point of solution would be to try directing your DNS requests through a public server such as Google DNS, Open DNS or Cloudfare DNS, and see if this improves things.

For Windows machines, this can be done by adjusting your TCP/IP settings under the network settings of your preferred network!

This will take all of your DNS request handling, away from your ISP.

 

Download and run Tweaking.com - Windows Repair.

Installer:

Portable:

Take your time and follow the instructions carefully.
It's recommended to run the program in "Safe Mode With Networking". Restart and run the program a second time.

 

Changed DNS, downloaded and ran Tweaking in safe and normal mode, no change, still can't access some pages.

 

What sort of internet connection do you have? Cable, DSL
Have you ever run any sort of TCP optimizing software for the current internet adapter?

 

I have cable.
No I have no run any TCP optimizing,

 

Try to ping 8.8.8.8 or try 216.239.38.120 (google). Will 127.0.0.1 ping? Did you run the network repair part of the tweaking tool?
Go into Setting and reset the network there. Go in Control Panel and Internet Options, under Advanced restore adv. settings and reset.

 

Pinged 8.8.8.8, 216.239.38.120 and 127.0.0.1, all timed out.
Did run network repair part of tweaking tool.went to control panel, internet options under advance restore adv. settings and reset.
No change in accessing some pages.

 

Check they're not blocked in the firewall. Make a rule to allow each in the outbound and inbound settings.

 

Go to device manager and remove and detect (reinstall) your adapter.

 

"Check they're not blocked in the firewall. Make a rule to allow each in the outbound and inbound settings."
Nothing outbound or inbound blocked.

 

"Go to device manager and remove and detect (reinstall) your adapter."
Tried to remove device 2 times, both times get a blue screen error.

 

Did you get the stop code? Go get bluescreenview from Nirsoft and start there.

 

Got bluescreenview from Nirsoft. It found 4 stop codes, all the same 0X1000007e, with caused by driver of insect.sys

 

Already plug into router, no change.
No processes that seem strange.
Running Avira Free Antivirus, scan found nothing
Firewall is Windows Firewall, nothing blocked in it.
No restore points prior to this happening
The computer is 9 plus years old, so I just got a new laptop, but I have not had time to set it up yet.
Thanks for all the help.

 

See if there is a newer driver for the network. Also you might boot into safe mode and try to delete the NIC. What is the OS?

 

OS is Win7.
Booted to safe mode, was able to load pages, deleted NIC, reinstalled, back to normal mode, was able to delete NIC and reinstall, still can't load the same pages.

 

Another software script (application, driver, setting etc) is interfering then.....Its not malicious, but its possible genuine (third-party) software may be the cause.
Tim might be able to pinpoint some suspects from your posted logs in Malware?
