For a while now I have been experiencing a very strange problem with my home internet service. For all of the computers in my network, I cannot connect to certain websites. Some of these are:


I also cannot connect to the update servers on my applications (such as windows update tool, malwarebytes update tool, zune updater, etc). The strange thing is that as soon as I connect to a different network (such as at a friend's house), all of the sites and updaters work perfectly fine, and I can access them from my laptop 100% of the time. I feel that my network setup is somehow blocking access to these sites. I currently have a cable modem + a Netgear WPN824 wireless router set up to manage my internet connection through Bright House. I recently reset my router to its default settings. I run windows 7 on my primary laptop, windows vista on another computer, and windows 97 on my third computer in the house.

Any information or help on the subject would be greatly appreciated!

Open up command prompt on the affected computers.

Type "ipconfig /flushdns" (without the quotes)
let it clear, don't worry if command prompt freezes for a couple of seconds.

Type "ipconfig /release" (without the quotes)

lastly type "ipconfig /renew" (once again without the quotes)

Clear cache in whatever browser you're using, and see if the problem is still there.

If the problem is still there type "tracert www.malwarebytes.org" in command prompt and post the results, feel free to block out the first 2 IPs, if its one of yours.

I see that you just finished malware removal for one of your computers in this network.

The symptoms you describe sound like one of the rootkit infections that's running around these days.

Both the other computer should be cleaned from malware. I don't recommend using them before cleaning

For each computer please do this:

Please follow the instructions in ==>This Guide<==.

Once the proper logs are created, then make a NEW TOPIC and post it ==>HERE<== Please a description of your computer issues and what you have done to resolve them.

If you can produce at least some of the logs, then please create the new topic and explain what happens when you try to create the log(s) that you couldn't get. If you cannot produce any of the logs, then still post the topic and explain that you followed the Prep. Guide, were unable to create the logs, and describe what happens when you try to create the logs.
