You will need to disconnect the wireless connection to the router and use an ethernet cable to attach the laptop directly to the modem. What you are dealing with is known as a
DNSChanger/DNShijacker .
Once the system is connected directly to the modem, open an Elevated Command Prompt by clicking the Start orb, in the Start Search field type in
cmdRight click cmd.exe and choose "Run as administrator", follow the prompts.
At the Elevated Command Prompt, type in the following, pressing Enter after each command
ipconfig /flushdnsexitNow see if you can download Malware Bytes Anti-Malware from **this link**
IF you can, then try to install MBAM. If it can not be installed, then try changing it's name to Dirt.exe or anything you'd like, as long as the .exe extension is not altered.
During the installation of MBAM allow it to update by making sure that a checkmark is present next to 'Update Malwarebytes' Anti-Malware '.
Once it's updated, boot to Safe Mode and do a Quick Scan of the system with MBAM, allowing it to remove whatever it detects.
A restart may be needed. If so, then restart the system to normal Windows mode.
Once in normal Windows mode, with the system still directly connected to the modem, see if you can download and run the
Malicious Software Removal Tool
IF you can do both of the above, then at least you've gained a foothold to battle the infection.
The next step would be to post to a reputable anti-malware forum for further assistance.
Please keep us posted as to your progress.
