Default Hosts file keeps changing every second

Hi There.

Since a while ago, I am having an issue with the hosts file located in
c:\windows\system32\drivers\etc, it keeps changing every second with weird
information. Here is the information:

201.114.35.200 bancomer.com
201.114.35.200 bancomer.com.mx
201.114.35.200 www.bancomer.com
201.114.35.200 www.bancomer.com.mx
192.193.230.100 www.banamex.com
192.193.230.100 banamex.com
192.193.230.100 www.banamex.com.mx
192.193.230.100 banamex.com.mx
200.76.36.117 www.bb.com.mx
200.76.36.117 bb.com.mx

I tried to use several antivirus and anti-spyware software, tried to stop
the DNS service but still the issue.
It would be great if you can provide me any help in this regarding.

Thanks

Alejandro.

Your computer is infected with malware.

Ordinarily, I do not counsel users to attempt to recover from malware
infections unless they feel comfortable with advanced repair procedures.
Better to show the computer to a professional.

This looks like a phishing Trojan which redirects accesses to bancomer.com
websites to a malicious site. If you are a Bancomer customer and have entered
any passwords into these pages, you should immediately change your online
passwords and inform your bank that your account may have been compromised.

Use SysInternals' FileMon to see what malware process is accessing the
hosts file.

Obviously whatever were the unidentified antivirus and anti-malware
software doesn't include HIPS (host intrustion protection system)
features to alert when a process is modifying the hosts file and prompt
you to allow or block that action.
