Windows XP - Hosts file has been tampered with

"Microsoft has this tutorial for you:

How do I reset the hosts file back to the default?

If necessary, do this in Safe Mode."

"This is typical of many malware apps. Do you have a good AV installed and up to date? Use other tools like Spybot Search and Destroy, Adaware amd Malwarebytes to scan. I would use all three. Double check that system restore is off and stays off. Be aware that some malware will block you from these sites and AV sites so you may have to download and install from alternate medis.

MalwareBytes

Spybot

Adaware"

I used winternals, found the Hosts file in C:\windows\system32\drivers\etc. proceeded to delete the file and then created a new one. Afterwards rebooted, ran all the anti malware and spyware removers.

You could try running ComboFix on your computer. This may fix the problem, some sort of malware.

Get to another computer and download the programs Combofix and SmitFraudFix. Boot into safe mode and run both. This should fix the problem.
