When you ping yahoo does it return "cannot find" or does it resolve to an IP and then times out?

Sounds like you have no DNS to me..

Mhat happens if you try a ping from a CMD prompt to say  PING WWW.GOOGLE.COM  
does that resolve to an address?  If not that confirms a DNS issue.

Check your DNS settings on the client.

OK that must be you have no or an invalid DNS server set in TCP/IP settings.

Normally you want both IP addess and DNS set to automatic, unless your router is not configured correctly!

What is set on there?

Must be then that the router is not getting a correct DNS server address.

Normally when its set to auto on your system, the PC will grab the router as a DNS server and the router will forward all DNS requests to the server it has as it;s DNS server.

Worth checking the router is set to get DNS automatically. Sometimes these are configured with a manual address which might be old now.

One thing you could try to confirm this is put a manual DNS server address in, you should get that from your provider.

Router gets DNS automatically.  I took this PC to my friends and canot get on internet there either so it cant be a router issue.  I can still get to google if i type ip address into IE.  I also pulled the HD and went through with Malwarebytes I did find a couple trojans.  Got them cleaned out, but still no internet i went back through and did ipconfig /flushdns....still nothing.

That sounds like the remnants of a DNS poison attack then. They can be a nightmare to get rid of!

If you have system restore points they would help as long as they were before the problem started!

Go through all of the Menu Items in "RogueKiller" (RK) and post the resultant logs.
It may be any number of things causing this, so please follow RK immediately with a FRESH download of Malwarebytes.

OK, try this.

Start cmd prompt
Type

nslookup
www.google.co.uk.
server 158.43.128.1
www.google.co.uk.
quit

There is an extra period after the domain names to resolve.
The first lookup will use your configured dns servers
The second will use a specific one on the internet.  This is one that has been around at least 15 years at Pipex and still good idea for resolving.

OpenDNS ones are another good idea: 208.67.222.222, 208.67.220.220

ipconfig /all will be good start to see, as would route print

drasmuss70,
I idea behind my suggest above was for you to run ALL six of the Menu Items in RogueKiller, and then immediately download, install,  and update a fresh copy of Malwarebytes.

After you have done all of that, post ALL of the logs that are generated by ALL of the activities.

Please try what is in http:#36933492.  It looks from above like pointing your DNS at your router is adding ".belkin" to the end of the reqeust, possibly down to the you have given to the router or it's dns name....

Results of ipconfig /all will really help.  As would amending your DNS setting from automatic to, say, the OpenDNS servers listed above.
