Hi, I ran malwarebytes and after it made me restart my pc i cannot connect to webpages and other services that require Internet even tough it shows that I have Internet access. Also note that I'm using my phone for this so I cannot download programs to fix it.

Did resetting Winsock say it completed successfully?

 

Reset TCP/IP

 

Same procedure as my post CMD > Right Click Run as Administrator

netsh int ip reset c:\resetlog.txt  <enter>

Reboot

It said it was successful for both of them and the second one didn't work either.

Open Internet Explorer 

 

  1. Open Internet Explorer by clicking the Start button 4f6cbd09-148c-4dd8-b1f2-48f232a2fd33_818. In the search box, type Internet Explorer, and then, in the list of results, click Internet Explorer.

  2. Click the Tools button, and then click Internet Options.

  3. Click the Connections tab, and then click LAN settings.

  4. Select the Use a proxy server for your LAN check box.   (Is the box checked? If it is uncheck it but make a note of any addresses in the box)

  5. After unchecking if checked see if you can access the internet

The box was unchecked and the port said 80. Also it's not just the browser it's also any programs that use Internet.

Type Troubleshooting in the search box. Click on "Connect to the internet". Let Windows try to repair the connection.

I think the only other options are as follows

 

Type CMD > Right Click > Run As Administrator and type the following

 

sfc /scannow   This will check for any missing or corrupt system files. After it finishes and you do not have internet access do the winsock reset again. If you still cannot connect then do the following:

 

Do a System Restore to a date before you cleaned the system with Malwarebytes. This should get your internet back and then go to the Virus Removal Forum, look at the posts at the beginning of the forum and attach the appropriate logs. Let the removal experts take a look at the problem. After you start a new thread there, post the link to your new thread here and a moderator will then lock this thread.

 

If the computer is OEM like a HP or Dell and the recovery partition is intact you could do a factory reset but you would need to backup all your data to an external hard drive and re-install any programs installed after purchase. Also you would need to download all security updates again. This is the nuclear option.

Did you try sfc /scannow?

 

When you go to Device Manager, do you see any yellow exclamation marks next to your network devices?

 

If you can get access to another computer you download netadapter repair to a USB flash drive, run it, and select Advanced Repair.

Does Malwarebytes let you restore from quarantine what it deleted?

 

If you create another user account, can you connect using the new account?

 

Look in Event Viewer for any System Errors. That may give you a clue on the connection problem.

 

Look in Services and compare it to the default services for Windows 7 SP1 here. Look especially at DNS and DHCP client services and see if they are started and on Automatic. The link is long so you may want a friend to print it out on their computer.

 

Other than doing a complete factory reset I am out of ideas, sorry. Hopefully other members can add any ideas they have regarding your problem.
